Wearable devices, such as smartwatches, fitness trackers, and health monitors, have become increasingly popular in recent years. These devices are designed to be worn on the body and can measure various physiological parameters, such as heart rate, blood pressure, and body temperature. Wearable devices can also track physical activity, sleep patterns, and even detect falls and accidents.

Body sensor networks (BSNs) take the concept of wearables to the next level. BSNs consist of a network of wearable sensors that can communicate with each other and with other devices. BSNs can provide real-time monitoring of multiple physiological parameters, making them useful for a range of applications, including medical monitoring, sports performance monitoring, and military applications.

Smart portable devices, such as smartphones and tablets, are also an essential component of the IoT ecosystem. These devices are not worn on the body, but they are portable and connected to the internet, allowing for seamless communication and data transfer. Smart portable devices can be used for a wide range of applications, such as mobile health, mobile banking, and mobile commerce.

The development of wearables, BSNs, and smart portable devices requires a unique set of skills and expertise, including embedded engineering. Embedded engineers are responsible for designing and implementing the hardware and software components that make these devices possible. Embedded engineers must have a deep understanding of electronics, sensors, microcontrollers, and wireless communication protocols.

One of the significant challenges of developing wearables, BSNs, and smart portable devices is power consumption. These devices are designed to be small, lightweight, and portable, which means that they have limited battery capacity. Therefore, embedded engineers must design devices that can operate efficiently with minimal power consumption. This requires careful consideration of power management strategies, such as sleep modes and low-power communication protocols.

Another challenge of developing wearables, BSNs, and smart portable devices is data management. These devices generate large volumes of data that need to be collected, processed, and stored. The data generated by these devices can be highly sensitive and may need to be protected from unauthorized access. Therefore, embedded engineers must design devices that can perform efficient data processing and storage while providing robust security features.

The communication protocols used by wearables, BSNs, and smart portable devices also present a significant challenge for embedded engineers. These devices use wireless communication protocols, such as Bluetooth and Wi-Fi, to communicate with other devices and the internet. However, the communication range of these protocols is limited, which can make it challenging to establish and maintain reliable connections. Embedded engineers must design devices that can operate efficiently in environments with limited communication range and intermittent connectivity.

Finally, the user interface and user experience of wearables, BSNs, and smart portable devices are critical for their success. These devices must be easy to use and intuitive, with a user interface that is designed for small screens and limited input methods. Embedded engineers must work closely with user experience designers to ensure that the devices are user-friendly and provide a seamless user experience.

We all know how IoT has revolutionized the way we interact with the world. IoT devices are now ubiquitous, from smart homes to industrial applications. A significant portion of these devices are Wireless Sensor Networks (WSNs), which are a key component of IoT systems. However, designing and implementing WSNs presents several challenges for embedded engineers. In this article, we discuss some of the significant challenges that embedded engineers face when working with WSNs.

WSNs are a network of small, low-cost, low-power, and wirelessly connected sensor nodes that can sense, process, and transmit data. These networks can be used in a wide range of applications such as environmental monitoring, healthcare, industrial automation, and smart cities. WSNs are typically composed of a large number of nodes, which communicate with each other to gather and exchange data. The nodes are equipped with sensors, microprocessors, transceivers, and power sources. The nodes can also be stationary or mobile, depending on the application.

One of the significant challenges of designing WSNs is the limited resources of the nodes. WSNs are designed to be low-cost, low-power, and small, which means that the nodes have limited processing power, memory, and energy. This constraint limits the functionality and performance of the nodes. Embedded engineers must design WSNs that can operate efficiently with limited resources. The nodes should be able to perform their tasks while consuming minimal power to maximize their lifetime.

Another challenge of WSNs is the limited communication range. The nodes communicate with each other using wireless radio signals. However, the range of the radio signals is limited, especially in indoor environments where the signals are attenuated by walls and other obstacles. The communication range also depends on the transmission power of the nodes, which is limited to conserve energy. Therefore, embedded engineers must design WSNs that can operate reliably in environments with limited communication range.

WSNs also present a significant challenge for embedded engineers in terms of data management. WSNs generate large volumes of data that need to be collected, processed, and stored. However, the nodes have limited storage capacity, and transferring data to a centralized location may not be practical due to the limited communication range. Therefore, embedded engineers must design WSNs that can perform distributed data processing and storage. The nodes should be able to process and store data locally and transmit only the relevant information to a centralized location.

Security is another significant challenge for WSNs. The nodes in WSNs are typically deployed in open and unprotected environments, making them vulnerable to physical and cyber-attacks. The nodes may also contain sensitive data, making them an attractive target for attackers. Embedded engineers must design WSNs with robust security features that can protect the nodes and the data they contain from unauthorized access.

The deployment and maintenance of WSNs present challenges for embedded engineers. WSNs are often deployed in harsh and remote environments, making it difficult to access and maintain the nodes. The nodes may also need to be replaced periodically due to the limited lifetime of the power sources. Therefore, embedded engineers must design WSNs that are easy to deploy, maintain, and replace. The nodes should be designed for easy installation and removal, and the network should be self-healing to recover from node failures automatically.

Final thought; WSNs present significant challenges for embedded engineers, including limited resources, communication range, data management, security, and deployment and maintenance. Addressing these challenges requires innovative design approaches that can maximize the performance and efficiency of WSNs while minimizing their cost and complexity. Embedded engineers must design WSNs that can operate efficiently with limited resources, perform distributed data processing and storage, provide robust security features, and be easy to deploy

Some say that if World War III breaks out, it will be fought in cyberspace. As IoT systems gather more and more under the “umbrella” of the network, security has never been more important to various user groups. From the traffic lights that play an important role in our urban traffic to the power system that provides energy for them, to the management and monitoring systems that keep cars running well, security in the use of networks and devices has become the basis and basis of modern communication devices and systems. necessary condition. Providing solid security in the online world is no easy task. Security is one of the very few scientific and technological means that must be confronted with external forces to achieve overdue results. What is more complicated is that these external forces can break through the defense line time after time through traditional and innovative means. Because of the many potential attack methods, information and network security has become an attractive and challenging topic, which is closely related to enterprises, industries and life.

For decades, the information technology (IT) environment has been very active and the hardest hit area for attacks and threats, which has also allowed IT to grow rapidly. In contrast, the operational technology (OT) environment is relatively traditional and closed, and the connection methods and channels between devices and the network are very limited. Therefore, compared with IT, OT records relatively fewer attack events, but its learning opportunities Countermeasures are also relatively scarce. But security in the OT world tends to have a broader security scope than IT. For example, in OT, security is almost equivalent to safety. In fact, the connected security standards of IIoT also incorporate the safety of equipment and people. This installment will focus on common challenges facing OT security.

The erosion problem of network architecture. The main issues facing the protection of industrial environments are initial design and ongoing maintenance. The original design concept stems from a premise that the network itself is safe, because it is isolated on the physical level of the enterprise, with little or no connection with the external environment, and the attacker lacks sufficient correlation knowledge to perform security attacks. In the vast majority of cases, the initial network design is sound, even good practice and relative standards. But in fact, from the point of view of security design, it is better to cope with the growing demand than to conceal the lack of communication and improve the response. It is relatively common that, over time, an otherwise hidden problem may be exposed by temporary updates and cracks to the hardware, allowing the problem to go unchecked and spread across the entire device family leading to a complete network and system crash Case.

Pervasive system legacy issues. In an industrial environment, the span of new and old equipment is large, the equipment life cycle is long, and the operating system of the equipment is not uniform enough, which makes the maintenance of the equipment extremely troublesome, and also exposes security issues such as system vulnerabilities. For example, in the context of urban power systems, it is not uncommon for older mechanical equipment to intersect with modern smart electronics. For the legacy components, because the old equipment cannot be connected to the network, the equipment is encouraged to run, but the entire system is integrated into the network, and some conditions cannot be monitored. From a security point of view, this situation is a potential threat, because many devices are likely to be unpatched or have vulnerabilities due to legacy issues, and it is more likely that the corresponding solutions for devices that are aging due to the passage of time cannot be applied. Therefore, we should strengthen the management of patches and devices, generate corresponding tools, and protect the vulnerabilities that may be exploited as much as possible.

Unsafe operating protocol. Among industrial control protocols, especially those based on serial ports, they are only considered for communication at the beginning of design, and there is no relative requirement for security. This has become the weakness and inherent loophole of the current network transmission protocol. In addition, the security considerations in the embedded operating system are relatively lacking. In old industrial protocols, data protocols such as monitoring and data acquisition often have coexisting security issues. Including the lack of communication authentication, static and dynamic data cannot establish effective protection, which makes the data in transmission often public. Although the data may not be so important, the risk of data tampering must be prevented.

The device is not secure. In addition to the defects of the communication protocol, the control equipment and the communication components themselves also have loopholes and defects. Before 2010, the world paid little attention to the security of industrial design, which also led to the fact that industrial design did not undergo the fire-zero test like IT, which led to frequent occurrence of vulnerability-related problems in the industry. This also reminds the OT industry to pay attention to the safety of the equipment itself.
IoT security issues are often more than that, including supplier dependence, security knowledge presentation and demonstration issues, etc. All these aspects remind the importance of safety all the time.

The serial server processes various data, maps the Ethernet interface of the TCP/IP protocol into a standard serial port, processes the serial data flow of the serial device, converts the format, and controls sending and receiving, making it a data frame that can be transmitted by the Ethernet, and judging the Ethernet Data frame, converted into a serial data transfer response to the serial device.
The system configures relevant network audio and video interface devices at each node to ensure the connection of audio and video signals. At the same time, each interface machine has a programmable control interface (RS-232, RS-485, IR infrared) to control the surrounding equipment. The control of each module can work independently, which means that the control failure of a module during the period will not affect the operation of the entire system, only the faulty node needs to be dealt with, which ensures the stable operation of the entire system and facilitates system maintenance.
Find the existing problems in time and eliminate them immediately. The system not only displays the corresponding parameters through the display screen. It should also communicate data through its own communication interface (RS-232 or RS-485 serial port). The original substations are generally managed by local computers without networking. Using RS serial port communication can meet the requirements. Now due to the gradual development of industrial Ethernet on the national grid.

Security considerations for eSIM and iSIM enabled secure connected services

Designing a secure connected product requires considerable thought and planning and there really is no ‘one-size-fits-all’ solution. How security should be implemented draws upon a multitude of factors, including:

• What data is being stored or transmitted between the device and other connected apps?
• Are there regulatory requirements for the device? (i.e. PCI DSS, HIPAA, FDA, etc.)
• What are the hardware or design limitations that will affect security implementation?
• Will the devices be manufactured in a site accredited by all of the necessary industry bodies?
• What is the expected lifespan of the device?

End-to-end ecosystem and services thinking needs to be a design consideration from the very early stage especially when considering the strain on battery consumption in devices such as wearables, smart watches and fitness devices as well as portable devices that are part of the connected consumer vehicles.

Originally posted here.

In my last post, I explored how OTA updates are typically performed using Amazon Web Services and FreeRTOS. OTA updates are critically important to developers with connected devices. In today’s post, we are going to explore several best practices developers should keep in mind with implementing their OTA solution. Most of these will be generic although I will point out a few AWS specific best practices.

Best Practice #1 – Name your S3 bucket with afr-ota

There is a little trick with creating S3 buckets that I was completely oblivious to for a long time. Thankfully when I checked in with some colleagues about it, they also had not been aware of it so I’m not sure how long this has been supported but it can help an embedded developer from having to wade through too many AWS policies and simplify the process a little bit.

Anyone who has attempted to create an OTA Update with AWS and FreeRTOS knows that you have to setup several permissions to allow an OTA Update Job to access the S3 bucket. Well if you name your S3 bucket so that it begins with “afr-ota”, then the S3 bucket will automatically have the AWS managed policy AmazonFreeRTOSOTAUpdate attached to it. (See Create an OTA Update service role for more details). It’s a small help, but a good best practice worth knowing.

Best Practice #2 – Encrypt your firmware updates

Embedded software must be one of the most expensive things to develop that mankind has ever invented! It’s time consuming to create and test and can consume a large percentage of the development budget. Software though also drives most features in a product and can dramatically different a product. That software is intellectual property that is worth protecting through encryption.

Encrypting a firmware image provides several benefits. First, it can convert your firmware binary into a form that seems random or meaningless. This is desired because a developer shouldn’t want their binary image to be easily studied, investigated or reverse engineered. This makes it harder for someone to steal intellectual property and more difficult to understand for someone who may be interested in attacking the system. Second, encrypting the image means that the sender must have a key or credential of some sort that matches the device that will decrypt the image. This can be looked at a simple source for helping to authenticate the source, although more should be done than just encryption to fully authenticate and verify integrity such as signing the image.

Best Practice #3 – Do not support firmware rollbacks

There is often a debate as to whether firmware rollbacks should be supported in a system or not. My recommendation for a best practice is that firmware rollbacks be disabled. The argument for rollbacks is often that if something goes wrong with a firmware update then the user can rollback to an older version that was working. This seems like a good idea at first, but it can be a vulnerability source in a system. For example, let’s say that version 1.7 had a bug in the system that allowed remote attackers to access the system. A new firmware version, 1.8, fixes this flaw. A customer updates their firmware to version 1.8, but an attacker knows that if they can force the system back to 1.7, they can own the system. Firmware rollbacks seem like a convenient and good idea, in fact I’m sure in the past I used to recommend them as a best practice. However, in today’s connected world where we perform OTA updates, firmware rollbacks are a vulnerability so disable them to protect your users.

Best Practice #4 – Secure your bootloader

Updating firmware Over-the-Air requires several components to ensure that it is done securely and successfully. Often the focus is on getting the new image to the device and getting it decrypted. However, just like in traditional firmware updates, the bootloader is still a critical piece to the update process and in OTA updates, the bootloader can’t just be your traditional flavor but must be secure.

There are quite a few methods that can be used with the onboard bootloader, but no matter the method used, the bootloader must be secure. Secure bootloaders need to be capable of verifying the authenticity and integrity of the firmware before it is ever loaded. Some systems will use the application code to verify and install the firmware into a new application slot while others fully rely on the bootloader. In either case, the secure bootloader needs to be able to verify the authenticity and integrity of the firmware prior to accepting the new firmware image.

It’s also a good idea to ensure that the bootloader is built into a chain of trust and cannot be easily modified or updated. The secure bootloader is a critical component in a chain-of-trust that is necessary to keep a system secure.

Best Practice #5 – Build a Chain-of-Trust

A chain-of-trust is a sequence of events that occur while booting the device that ensures each link in the chain is trusted software. For example, I’ve been working with the Cypress PSoC 64 secure MCU’s recently and these parts come shipped from the factory with a hardware-based root-of-trust to authenticate that the MCU came from a secure source. That Root-of-Trust (RoT) is then transferred to a developer, who programs a secure bootloader and security policies onto the device. During the boot sequence, the RoT verifying the integrity and authenticity of the bootloader, which then verifies the integrity and authenticity of any second stage bootloader or software which then verifies the authenticity and integrity of the application. The application then verifies the authenticity and integrity of its data, keys, operational parameters and so on.

This sequence creates a Chain-Of-Trust which is needed and used by firmware OTA updates. When the new firmware request is made, the application must decrypt the image and verify that authenticity and integrity of the new firmware is intact. That new firmware can then only be used if the Chain-Of-Trust can successfully make its way through each link in the chain. The bottom line, a developer and the end user know that when the system boots successfully that the new firmware is legitimate. 

Conclusions

OTA updates are a critical infrastructure component to nearly every embedded IoT device. Sure, there are systems out there that once deployed will never update, however, those are probably a small percentage of systems. OTA updates are the go-to mechanism to update firmware in the field. We’ve examined several best practices that developers and companies should consider when they start to design their connected systems. In fact, the bonus best practice for today is that if you are building a connected device, make sure you explore your OTA update solution sooner rather than later. Otherwise, you may find that building that Chain-Of-Trust necessary in today’s deployments will be far more expensive and time consuming to implement.

Without mindful and strategic investments, a company’s supply chain could become wedged in its own proverbial Suez Canal, ground to a halt by outside forces and its inflexible, complex systems.

It’s a dramatic image, but one that became reality for many companies in the last year. Supply chain failures aren’t typically such high-profile events as the Suez Canal blockage, but rather death by a thousand inefficiencies, each slowing business operations and affecting the customer experience.

Delay by delay and spreadsheet by spreadsheet, companies are at risk of falling behind more nimble, cloud-enabled competitors. And as we emerge from the pandemic with a new understanding of how important adaptable, integrated supply chains are, company leaders have critical choices to make.

The Hannover Messe conference (held online from April 12-16) gives manufacturing and supply chain executives around the world a chance to hear perspectives from industry leaders and explore the latest manufacturing and supply chain technologies available.

Technology holds great promise. But if executives don’t ask key strategic questions to supply chain software vendors, they could unknowingly introduce a range of operational and strategic obstacles into their company’s future.

If you’re attending Hannover Messe, here are a few critical questions to ask:

Are advanced technologies like machine learning, IoT, and blockchain integrated into your supply chain applications and business processes, or are they addressed separately?

It’s important to go beyond the marketing. Is the vendor actually promoting pilots of advanced technologies that are simply customized use cases for small parts of an overall business process hosted on a separate platform? If so, it may be up to your company to figure out how to integrate it with the rest of that vendor’s applications and to maintain those integrations.

To avoid this situation, seek solutions that have been purpose-built to leverage advanced technologies across use cases that address the problems you hope to solve. It’s also critical that these solutions come with built-in connections to ensure easy integration across your enterprise and to third party applications.

Are your applications or solutions written specifically for the cloud?

If a vendor’s solution for a key process (like integrated business planning or plan to produce, for example) includes applications developed over time by a range of internal development teams, partners, and acquired companies, what you’re likely to end up with is a range of disjointed applications and processes with varying user interfaces and no common data model. Look for a cloud solution that helps connect and streamline your business processes seamlessly.

Update schedules for the various applications could also be disjointed and complicated, so customers can be tempted to skip updates. But some upgrades may be forced, causing disruption in key areas of your business at various times.

And if some of the applications in the solution were written for the on-premises world, business processes will likely need customization, making them hard-wired and inflexible. The convenience of cloud solutions is that they can take frequent updates more easily, resulting in greater value driven by the latest innovations.

Are your supply chain applications fully integrated—and can they be integrated with other key applications like ERP or CX?

A lack of integration between and among applications within the supply chain and beyond means that end users don’t have visibility into the company’s operations—and that directly affects the quality and speed of business decisions. When market disruptions or new opportunities occur, unintegrated systems make it harder to shift operations—or even come to an agreement on what shift should happen.

And because many key business processes span multiple areas—like manufacturing forecast to plan, order to cash, and procure to pay—integration also increases efficiency. If applications are not integrated across these entire processes, business users resort to pulling data from the various systems and then often spend time debating whose data is right.

Of course, all of these issues increase operational costs and make it harder for a company to adapt to change. They also keep the IT department busy with maintenance tasks rather than focusing on more strategic projects.

Do you rely heavily on partners to deliver functionality in your supply chain solutions?

Ask for clarity on which products within the solution belong to the vendor and which were developed by partners. Is there a single SLA for the entire solution? Will the two organizations’ development teams work together on a roadmap that aligns the technologies? Will their priority be on making a better solution together or on enhancements to their own technology? Will they focus on enabling data to flow easily across the supply chain solution, as well as to other systems like ERP? Will they be able to overcome technical issues that arise and streamline customer support?

It’s critical for supply chain decision-makers to gain insight into these crucial questions. If the vendor is unable to meet these foundational needs, the customer will face constant obstacles in their supply chain operations.

For midstream oil and gas operators, data flow can be as important as product flow. The operator’s job is to safely move oil and natural gas from its extraction point (upstream), to where it’s converted to fuels (midstream), to customer delivery locations (downstream). During this process, pump stations, meter stations, storage sites, interconnection points, and block valves generate a substantial volume and variety of data that can lead to increased efficiency and safety.

“Just one pipeline pump station might have 6 Programmable Logic Controllers (PLCs), 12 flow computers, and 30 field instruments, and each one is a source of valuable operational information,” said Mike Walden, IT and SCADA Director for New Frontier Technologies, a Cisco IoT Design-In Partner that implements OT and IT systems for industrial applications. Until recently, data collection from pipelines was so expensive that most operators only collected the bare minimum data required to comply with industry regulations. That data included pump discharge pressure, for instance, but not pump bearing temperature, which helps predict future equipment failures.

A turnkey solution to modernize midstream operations

Now midstream operators are modernizing their pipelines with Industrial Internet of Things (IIoT) solutions. Cisco and New Frontier Technologies have teamed up to offer a solution combining the Cisco 1100 Series Industrial Integrated Services Router, Cisco Edge Intelligence, and New Frontier’s know-how. Deployed at edge locations like pump stations, the solution extracts data from pipeline equipment and is sent via legacy protocols, transforming data at the edge to a format that analytics and other enterprise applications understand. The transformation also minimizes bandwidth usage.

Mike Walden views the Cisco IR1101 as a game-changer for midstream operators. He shared with me that “Before the Cisco IR1101, our customers needed four separate devices to transmit edge data to a cloud server—a router at the pump station, an edge device to do protocol conversion from the old to the new, a network switch, and maybe a firewall to encrypt messages…With the Cisco IR1101, we can meet all of those requirements with one physical device.”

Collect more data, at almost no extra cost

Using this IIoT solution, midstream operators can for the first time:

• Collect all available field data instead of just the data on a polling list. If the maintenance team requests a new type of data, the operations team can meet the request using the built-in protocol translators in Edge Intelligence. “Collecting a new type of data takes almost no extra work,” Mike said. “It makes the operations team look like heroes.”
• Collect data more frequently, helping to spot anomalies. Recording pump discharge pressure more frequently, for example, makes it easier to detect leaks. Interest in predicting (rather than responding to) equipment failure is also growing. The life of pump seals, for example, depends on both the pressure that seals experience over their lifetime and the peak pressures. “If you only collect pump pressure every 30 minutes, you probably missed the spike,” Mike explained. “If you do see the spike and replace the seal before it fails, you can prevent a very costly unexpected outage – saving far more than the cost of a new seal.”
• Protect sensitive data with end-to-end security. Security is built into the IR1101, with secure boot, VPN, certificate-based authentication, and TLS encryption.
• Give IT and OT their own interfaces so they don’t have to rely on the other team. The IT team has an interface to set up network templates to make sure device configuration is secure and consistent. Field engineers have their own interface to extract, transform, and deliver industrial data from Modbus, OPC-UA, EIP/CIP, or MQTT devices.

As Mike summed it up, “It’s finally simple to deploy a secure industrial network that makes all field data available to enterprise applications—in less time and using less bandwidth.”

“The End of Cloud Computing.” “The Edge Will Eat The cloud.” “Edge Computing—The End of Cloud Computing as We Know It.”  

Such headlines grab attention, but don’t necessarily reflect reality—especially in Industrial Internet of Things (IoT) deployments. To be sure, edge computing is rapidly emerging as a powerful force in turning industrial machines into intelligent machines, but to paraphrase Mark Twain: “The reports of the death of cloud are greatly exaggerated.” 

The Tipping Point: Edge Computing Hits Mainstream

We’ve all heard the stats—billions and billions of IoT devices, generating inconceivable amounts of big data volumes, with trillions and trillions of U.S. dollars to be invested in IoT over the next several years. Why? Because industrials have squeezed every ounce of productivity and efficiency out of operations over the past couple of decades, and are now looking to digital strategies to improve production, performance, and profit. 

The Industrial Internet of Things (IIoT) represents a world where human intelligence and machine intelligence—what GE Digital calls minds and machines—connect to deliver new value for industrial companies. 

In this new landscape, organizations use data, advanced analytics, and machine learning to drive digital industrial transformation. This can lead to reduced maintenance costs, improved asset utilization, and new business model innovations that further monetize industrial machines and the data they create. 

Despite the “cloud is dead” headlines, GE believes the cloud is still very important in delivering on the promise of IIoT, powering compute-intense workloads to manage massive amounts of data generated by machines. However, there’s no question that edge computing is quickly becoming a critical factor in the total IIoT equation.

Computer vision is fundamental to capturing real-world data within the IoT. Arm technology provides a secure ecosystem for smart cameras in business, industrial and home applications

By Mohamed Awad, VP IoT & Embedded, Arm

Computer vision leverages artificial intelligence (AI) to enable devices such as smart cameras to interpret and understand what is happening in an image. Recreating a sensor as powerful as the human eye with technology opens up a wide and varied range of use cases for computers to perform tasks that previously required human sight – so it’s no wonder that computer vision is quickly becoming one of the most important ways to capture and act on real-world data within the Internet of Things (IoT).

Smart cameras now use computer vision in a range of business and industrial applications, from counting cars in parking lots to monitoring footfall in retail stores or spotting defects on a production line. And in the home, smart cameras can tell us when a package has been delivered, whether the dog escaped from the back yard or when our baby is awake.

Across the business and consumer worlds, the adoption of smart camera technology is growing exponentially. In its 2020 report “Cameras and Computing for Surveillance and Security”, market research and strategy consulting company Yole Développement estimates that for surveillance alone, there are approximately one billion cameras across the world. That number of installations is expected to double by 2024.

This technology features key advancements in security, heterogeneous computing, image processing and cloud services – enabling future computer vision products that are more capable than ever.

Smart camera security is top priority for computer vision

IoT security is a key priority and challenge for the technology industry. It’s important that all IoT devices are secure from exploitation by malicious actors, but it’s even more critical when that device captures and stores image data about people, places and high-value assets.

Unauthorized access to smart cameras tasked with watching over factories, hospitals, schools or homes would not only be a significant breach of privacy, it could also lead to untold harm—from plotting crimes to the leaking of confidential information. Compromising a smart camera could also provide a gateway, giving a malicious actor access to other devices within the network – from door, heating and lighting controls to control over an entire smart factory floor.

We need to be able to trust smart cameras to maintain security for us all, not open up new avenues for exploitation. Arm has embraced the importance of security in IoT devices for many years through its product portfolio offerings such as Arm TrustZone for both Cortex-A and Cortex-M.

In the future, smart camera chips based on the Armv9 architecture will add further security enhancements for computer vision products through the Arm Confidential Compute Architecture (CCA).

Further to this, Arm promotes common standards of security best practice such as PSA Certified and PARSEC. These are designed to ensure that all future smart camera deployments have built-in security, from the point the image sensor first records the scene to storage, whether that data is stored locally or in the cloud by using advanced security and data encryption techniques.

Endpoint AI powers computer vision in smart camera devices

The combination of image sensor technology and endpoint AI is enabling smart cameras to infer increasingly complex insights from the vast amounts of computer vision data they capture. New machine learning capabilities within smart camera devices meet a diverse range of use cases – such as detecting individual people or animals, recognizing specific objects and reading license plates. All of these applications for computer vision require ML algorithms running on the endpoint device itself, rather than sending data to the cloud for inference. It’s all about moving compute closer to data.

For example, a smart camera employed at a busy intersection could use computer vision to determine the number and type of vehicles waiting at a red signal at various hours throughout the day. By processing its own data and inferring meaning using ML, the smart camera could automatically adjust its timings in order to reduce congestion and limit build-up of emissions automatically without human involvement.

Arm’s investment in AI for applications in endpoints and beyond is demonstrated through its range of Ethos machine learning processors: highly scalable and efficient NPUs capable of supporting a range of 0.1 to 10 TOP/s through many-core technologies. Software also plays a vital role in ML and this is why Arm continues to support the open-source community through the Arm NN SDK and TensorFlow Lite for Microcontrollers (TFLM) open-source frameworks.

These machine learning workload frameworks are based on existing neural networks and power-efficient Arm Cortex-A CPUs, Mali GPUs and Ethos NPUs as well as Arm Compute library and CMSIS-NN – a collection of low-level machine learning functions optimized for Cortex-A CPU, Cortex-M CPU and Mali GPU architectures.

The Armv9 architecture supports enhanced AI capabilities, too, by providing accessible vector arithmetic (individual arrays of data that can be computed in parallel) via Scalable Vector Extension 2 (SVE2). This enables scaling of the hardware vector length without having to rewrite or recompile code. In the future, extensions for matrix multiplication (a key element in enhancing ML) will push the AI envelope further.

Smart cameras connected in the cloud

Cloud and edge computing is also helping to expedite the adoption of smart cameras. Traditional CCTV architectures saw camera data stored on-premises via a Network Video Recorder (NVR) or a Digital Video Recorder (DVR). This model had numerous limitations, from the vast amount of storage required to the limited number of physical connections on each NVR.

Moving to a cloud-native model simplifies the rollout of smart cameras enormously: any number of cameras can be provisioned and managed via a configuration file downloaded to the device. There’s also a virtuous cycle at play: Data from smart cameras can be now used to train the models in the cloud for specific use-cases so that cameras become even smarter. And the smarter they become, the less data they need to send upstream.

The use of cloud computing also enables automation of processes via AI sensor fusion by combining computer vision data from multiple smart cameras. Taking our earlier example of the smart camera placed at a road intersection, cloud AI algorithms could combine data from multiple cameras to constantly adjust traffic light timings holistically across an entire city, keeping traffic moving.

Arm enables the required processing continuum from cloud to endpoint. Cortex-M microcontrollers and Cortex-A processors power smart cameras, with Cortex-A processors also powering edge gateways. Cloud and edge servers harness the capabilities of the Neoverse platform.

New hardware and software demands on smart cameras

The compute needs for computer vision devices continue to grow year over year, with ultra-high resolution video capture (8K 60fps) and 64-bit (Armv8-A) processing marking the current standard for high-end smart camera products.

As a result, the system-on-chip (SoC) within next-generation smart cameras will need to embrace heterogenous architectures, combining CPUs, GPUs, NPUs alongside dedicated hardware for functions like computer vision, image processing, video encoding and decoding.

Storage, too, is a key concern: While endpoint AI can reduce storage requirements by processing images locally on the camera, many use cases will require that data be retained somewhere for safety and security – whether on the device, in edge servers or in the cloud.

To ensure proper storage of high-resolution computer vision data, new video encoding and decoding standards such as H.265 and AV1 are becoming the de facto standard.

New use cases driving continuous innovation

Overall, the demands from the new use cases are driving the need for continuous improvement in computing and imaging technologies across the board.

When we think about image-capturing devices such as CCTV cameras today, we should no longer imagine grainy images of barely recognizable faces passing by a camera. Advancements in computer vision – more efficient and powerful compute coupled with the intelligence of AI and machine learning – are making smart cameras not just image sensors but image interpreters. This bridge between the analog and digital worlds is opening up new classes of applications and use cases that were unimaginable a few years ago.

Unless you have been living under a rock, you have been seeing and hearing a lot about&nbsp5G these days. In addition, if you are at all involved in Internet of Things (IoT) or other initiatives at your organization that use cellular networking technologies, you have also likely heard about 5G New Radio, otherwise known as 5G NR, the new 5G radio access technology specification.

However, all the jargon, hype, and sometimes contradictory statements made by solution providers, the media, and analysts regarding 5G and 5G NR can make it difficult to understand what 5G NR actually is, how it works, what its advantages are, to what extent it is different than other cellular radio access technologies, and perhaps most importantly, how your organization can use this new radio access technology.

In this blog, we will provide you with an overview on 5G NR, offering you answers to these and other basic 5G NR questions – with a particular focus on what these answers mean for those in the IoT industry. 

We can’t promise to make you a 5G NR expert with this blog – but we can say that if you are confused about 5G NR before reading it, you will come away afterward with a better understanding of what 5G NR is, how it works, and how it might transform your industry.

What is the NR in 5G NR?

As its name implies, 5G New Radio or 5G NR is the new radio access technology specification found in the 5G standard. 

Set by the 3rd Generation Partnership Project (3GPP) telecommunications standards group, the 5G NR specification defines how 5G NR edge devices (smart phones, embedded modules, routers, and gateways) and 5G NR network infrastructure (base stations, small cells, and other Radio Access Network equipment) wirelessly transmit data. To put it another way, 5G NR describes how 5G NR edge devices and 5G NR network infrastructure use radio waves to talk to each other. 

5G NR is a very important part of 5G. After all, it describes how 5G solutions will use radio waves to wirelessly transmit data faster and with less latency than previous radio access technology specifications. However, while 5G NR is a very important part of the new 5G standard, it does not encompass everything related to 5G. 

For example, 5G includes a new core network architecture standard (appropriately named 5G Core Network or 5GCN) that specifies the architecture of the network that collects, processes, and routes data from edge devices and then sends this data to the cloud, other edge devices, or elsewhere. The 5GCN will improve 5G networks’ operational capacity, efficiency, and performance.

However, 5GCN is not a radio access technology like 5G NR, but rather a core network technology. In fact, networks using the 5GCN core network will be able to work with previous types of radio access technologies – like LTE. 

Is 5G NR one of 5G’s most important new technological advancements? Yes. But it is not the only technological advancement to be introduced by 5G.  

How does 5G NR work?

Like all radio access communications technology specifications, the 5G NR specification describes how edge devices and network infrastructure transmit data to each other using electromagnetic radio waves. Depending on the frequency of the electromagnetic waves (how long the wave is), it occupies a different part of the wireless spectrum.

Some of the waves that 5G NR uses have frequencies of between 400 MHz and 6 GHz. These waves occupy what is called sub-6 spectrum (since their frequencies are all under 6 GHz).

This sub-6 spectrum is used by other cellular radio access technologies, like LTE, as well. In the past, using different cellular radio access technologies like this over the same spectrum would lead to unmanageable interference problems, with the different technologies radio waves interfering with each other. 

One of 5G NR’s many advantages is that it’s solved this problem, using a technology called Dynamic Spectrum Sharing (DSS). This DSS technology allows 5G NR signals to use the same band of spectrum as LTE and other cellular technologies, like LTE-M and NB-IoT. This allows 5G NR networks to be rolled out without shutting down LTE or other networks that support existing LTE smart phones or IoT devices. You can learn more about DSS, and how it speeds the rollout of 5G NR while also extending the life of IoT devices, here.

One of 5G NR’s other major advancements is that it does not just use waves in the sub-6 spectrum to transmit data. The 5G NR specification also specifies how edge devices and network infrastructure can use radio waves in bands between 24 GHz and 52 GHz to transmit data.

These millimeter wave (mmWave) bands greatly expand the amount of spectrum available for wireless data communications. The lack of spectrum capacity has been a problem in the past, as there is a limited number of bands of sub-6 spectrum available for organizations to use for cellular communications, and many of these bands are small. Lack of available capacity and narrow spectrum bands led to network congestion, which limits the amount of data that can be transmitted over networks that use sub-6 spectrum. 

mmWave opens up a massive amount of new wireless spectrum, as well as much broader bands of wireless spectrum for cellular data transmission. This additional spectrum and these broader spectrum bands increase the capacity (amount of data) that can be transmitted over these bands, enabling 5G NR mmWave devices to achieve data speeds that are four or more times faster than devices that use just sub-6 spectrum. 

The additional wireless capacity provided by mmWave also reduces latency (the time between when device sends a signal and when it receives a response). By reducing latency from 10 milliseconds with sub-6 devices to 3-4 milliseconds or lower with 5G NR mmWave devices, 5G enables new industrial automation, autonomous vehicle and immersive gaming use cases, as well as Virtual Reality (VR), Augmented Reality (AR), and similar Extended Reality (XR) use cases, all of which require very low latency. 

On the other hand, these new mmWave devices and network infrastructure come with new technical requirements, as well as drawbacks associated with their use of mmWave spectrum. For example, mmWave devices use more power and generate more heat than sub-6 devices. In addition, mmWave signals have less range and do not penetrate walls and other physical objects as easily as sub-6 waves. 5G NR includes some technologies, such as beamforming and massive Multiple Input Multiple Output (MIMO) that lessen some of these range and obstacle penetration limitations – but they do not eliminate them. 

To learn more about the implications of 5G NR mmWave on the design of IoT and other products, read our blog, Seven Tips For Designing 5G NR mmWave Products.

In addition, there has been a lot written on these two different “flavors” (sub-6 and mmWave) of 5G NR. If you are interested in learning more about the differences between sub-6 5G NR and mmWave 5G NR, and how together they enable both evolutionary and revolutionary changes for Fixed Wireless Access (FWA), mobile broadband, IoT and other wireless applications, read our previous blog A Closer Look at the Five Waves of 5G.

What is the difference between 5G NR and LTE?

Though sub-6 and mmWave are very different, both types of 5G NR provide data transfer speed, latency, and other performance improvements compared to LTE, the previous radio access technology specification used for cellular communications. 

For example, outside of its use of mmWave, 5G NR features other technical advancements designed to improve network performance, including:

• Flexible numerology, which enables 5G NR network infrastructure to set the spacing between subcarriers in a band of wireless spectrum at 15, 30, 60, 120 and 240 kHz, rather than only use 15 kHz spacing, like LTE. This flexible numerology is what allows 5G NR to use mmWave spectrum in the first place. It also improves the performance of 5G NR devices that use higher sub-6 spectrum, such as 3.5 GHz C-Band spectrum, since the network can adjust the subcarrier spacing to meet the particular spectrum and use case requirements of the data it is transmitting. For example, when low latency is required, the network can use wider subcarrier spacing to help improve the latency of the transmission.
• Beamforming, in which massive MIMO (multiple-input and multiple-output) antenna technologies are used to focus wireless signal and then sweep them across areas till they make a strong connection. Beamforming helps extend the range of networks that use mmWave and higher sub-6 spectrum.  
• Selective Hybrid Automatic Repeat Request (HARQ), which allows 5G NR to break large data blocks into smaller blocks, so that when there is an error, the retransmission is smaller and results in higher data transfer speeds than LTE, which transfers data in larger blocks. 
• Faster Time Division Duplexing (TDD), which enables 5G NR networks to switch between uplink and downlink faster, reducing latency. 
• Pre-emptive scheduling, which lowers latency by allowing higher-priority data to overwrite or pre-empt lower-priority data, even if the lower-priority data is already being transmitted. 
• Shorter scheduling units that trim the minimum scheduling unit to just two symbols, improving latency.
• A new inactive state for devices. LTE devices had two states – idle and connected. 5G NR includes a new state – inactive – that reduces the time needed for an edge device to move in and out of its connected state (the state used for transmission), making the device more responsive. 

These and the other technical advancements made to 5G NR are complicated, but the result of these advancements is pretty simple – faster data speeds, lower latency, more spectrum agility, and otherwise better performance than LTE. 

Are LPWA radio access technology specifications, like NB-IoT and LTE-M, supported by 5G?

Though 5G features a new radio access technology, 5G NR, 5G supports other radio access technologies as well. This includes the Low Power Wide Area (LPWA) technologies, Narrowband IoT (NB-IoT), and Long Term Evolution for Machines (LTE-M). In fact, these LPWA standards are the standards that 5G uses to address one of its three main use cases – Massive, Machine-Type Communications (mMTC). 

Improvements have been and continue to be made to these 5G LPWA standards to address these mMTC use cases – improvements that further lower the cost of LPWA devices, reduce these devices’ power usage, and enable an even larger number of LPWA devices to connect to the network in a given area.

What are the use cases for 5G NR and 5G LPWA Radio Access Technologies?

Today, LTE supports three basic use cases:

• Voice: People today can use LTE to talk to each other using mobile devices. 
• Mobile broadband (MBB): People can use smartphones, tablets, mobile and other edge devices to view videos, play games, and use other applications that require broadband data speeds.
• IoT: People can use cellular modules, routers, and other gateways embedded in practically anything – a smart speaker, a dog collar, a commercial washing machine, a safety shoe, an industrial air purifier, a liquid fertilizer storage tank – to transmit data from the thing to the cloud or a private data center and back via the internet.  

5G NR, as well as 5G’s LPWA radio access technologies (NB-IoT and LTE-M) will continue to support these existing IoT and voice use cases. 

However, 5G also expands on the MBB use case with a new Enhanced Mobile Broadband (eMBB) use case. These eMBB use cases leverage 5G NR’s higher peak and average speeds and lower latency to enable smart phones and other devices to support high-definition cloud-based immersive video games, high quality video calls and new VR, AR, and other XR applications.

In addition, 5G NR also supports a new use case, called Ultra-Reliable, Low-Latency Communications (URLLC). 5G NR enables devices to create connections that are ultra-reliable with very low latency. With these new 5G NR capabilities, as well as 5G NR’s support for very fast handoffs and high mobility, organizations can now deploy new factory automation, smart city 2.0 and other next generation Industrial IoT (IIoT) applications, as well as Vehicle-to-everything (V2X) applications, such as autonomous vehicles. 

As we mentioned above, 5G will also support the new mMTC use case, which represents an enhancement of the existing IoT use case. However, in the case of mMTC, new use cases will be enabled by improvements to LTE-M and NB-IoT radio access technology standards, not 5G NR. Examples of these types of new mMTC use cases include large-scale deployments of small, low cost edge devices (like sensors) for smart city, smart logistics, smart grid, and similar applications.

But this is not all. 3GPP is looking at additional new use cases (and new technologies for these use cases), as discussed in this recent blog on Release 17 of the 5G standard. One of these new technologies is a new Reduced Capability (RedCap) device – sometimes referred to as NR Light – for IoT or MTC use cases that require faster data speeds than LPWA devices can provide, but also need devices that are less expensive than the 5G NR devices being deployed today.

3GPP is also examining standard changes to NR, LTE-M, and NB-IoT in 5G Release 17 that would make it possible for satellites to use these technologies for Non-Terrestrial Network (NTN) communications. This new NTN feature would help enable the deployment of satellites able to provide NR, LTE-M, and NB-IoT coverage in very remote areas, far away from cellular base stations.

What should you look for in a 5G NR module, router or gateway solution?

While all 5G NR edge devices use the 5G NR technology specification, they are not all created equal. In fact, the flexibility, performance, quality, security, and other capabilities of a 5G NR edge device can make the difference between a successful 5G NR application rollout and a failed one. 

As they evaluate 5G NR edge devices for their application, organizations should ask themselves the following questions:

• Is the edge device multi-mode? 
While Mobile Network Operators (MNOs) are rapidly expanding their 5G NR networks, there are still many areas where 5G NR coverage is not available. Multi-mode edge devices that can support LTE, or even 3G, help ensure that wherever the edge device is deployed, it will be able to connect to a MNO’s network – even if this connection does not provide the data speed, latency, or other performance needed to maximize the value of the 5G NR application. 

In addition, many MNOs are rolling out non-standalone (NSA) 5G NR networks at first. These NSA 5G NR networks need a LTE connection in addition to a 5G NR connection to transmit data from and to 5G NR devices. If your edge device does not include support for LTE, it will not be able to use 5G NR on these NSA networks. 

• How secure are the edge devices? 
Data is valuable and sensitive – and the data transmitted by 5G NR devices is no different. To limit the risk that this data is exposed, altered, or destroyed, organizations need to adopt a Defense in Depth approach to 5G NR cybersecurity, with layers of security implemented at the cloud, network, and edge device levels. 

At the edge device level, organizations should ensure their devices have security built-in with features such as HTTPS, secure socket, secure boot, and free unlimited firmware over-the-air (FOTA) updates. 

Organizations will also want to use edge devices from trustworthy companies that are headquartered in countries that have strict laws in place to protect customer data. In doing so you will ensure these companies are committed to working with you to prevent state or other malicious actors from gaining access to your 5G NR data.

• Are the 5G NR devices future-proof? 
Over time, organizations are likely to want to upgrade their applications. In addition, the 5G NR specification is not set in stone, and updates to it are made periodically. Organizations will want to ensure their 5G NR edge devices are futureproof, with capabilities that include the ability to update them with new firmware over the air, so they can upgrade their applications and take advantage of new 5G NR capabilities in the future. 

• Can the 5G NR device do edge processing? 
While 5G NR increases the amount of data that can be transmitted over cellular wireless networks, in many cases organizations will want to filter, prioritize, or otherwise process some of their 5G NR application’s data at the edge. This edge processing can enable these organizations to lower their data transmission costs, improve application performance, and lower their devices energy use. 

5G NR edge devices that offer organizations the ability to easily process data at the edge allow them to lower their data transmission expenses, optimize application performance, and maximize their devices’ battery lives.

Look around you, and you’ll find at least 4 objects in your house with the word ‘smart’. Your TV, your phone, maybe even your fridge. All of our appliances are increasingly being connected to the internet.

This interconnection of ‘smart’ objects is referred to as the Internet of Things (IoT). In less than a decade, we’ve pushed communication technology to its limits.

Now you can talk to your microwave from your phone. With over 20 billion devices part of the IoT phenomenon, our lives are more connected than ever before. But, there's a flip side to this technological revolution.

There are a lot of IoT security risks that arise from the vulnerabilities of the devices. Over 200 million individual IoT attacks were tracked in 2020 alone.

Hackers can take advantage of vulnerabilities to steal your data, or to use your devices to conduct attacks. This blog will take you through the procedures you can adopt to secure your life from cybercriminals.

Overview of IoT

Internet Protocol Version 4 (IPv4) is the protocol that is the process through which our devices connect with the internet.

When the internet is accessed, a unique identity protocol is generated Recently, however, IPv4 has been running out of physical addresses. To fix this, IPv6 was introduced that has the capacity for trillions of trillions of physical addresses. It also offers improvements to connectivity, performance, and security. 

IoT has already been used extensively to provide ease to human life, with some of the many applications being innocuous.

• Home Automation - Phones are now being used to connect with most homes to your electric circuits, your TV, AC Fridge, and more. This has simplified lives while improving productivity and efficiency. Many of these devices also optimise themselves, for instance, an AC that adjusts temperature itself based on the environment.
• Smart Cities - By far the most awaited feature of IoT. Smart Cities promise to revolutionize the way you live. Not only will they reduce costs, but they would also improve efficiency. Road signals would be able to manage traffic congestions, and parking sensors would inform you of empty spots.
• Drones - Drones are increasingly being used to simplify our lives. Right from being used by Amazon as delivery agents, to being used by government bodies for firefighting activities, drones are revolutionizing the tech space.
• Medical Applications - Smartwatches monitor a person’s health and can call them an ambulance when at risk. Ambulances that can connect to the road signals and clear a path. 
• Smart Phones - Your phone will most likely be the key to controlling the IoT. Already many appliances connect to your phone, and many more may soon follow. VR and AR have made great leaps forward, allowing people to do much more than simply call people with their phones.

Threats of IoT

IoT suffers from similar vulnerabilities that hackers attempt to use to their advantage. They use these devices to either steal personal data or to connect them to a botnet. According to Symantec, IoT attacks have increased a 1000% since 2016, with routers and security cameras being the most attacked.

• Botnet - A botnet is essentially a large collection of IoT that hackers can be used to make large coordinated attacks on other services. Botnets are easy to create, with IoT being a favored target due to their weaker security.
• Shadow IoT - Losing control of your devices can be terrifying. Researchers have already proved it possible to stall the engines of smart cars too. Many industries use SCADA systems, a massive computer overseer. Were this to be compromised, it could lead to catastrophe, including nuclear meltdowns in the worst case. 
• Data Theft - The most common threat. Data can be extracted not only from the compromised device but all on the network. This can be catastrophic for your business. Losing the data of millions of users can erode their trust in your services. 

Applying Penetration Testing to circumvent IoT Attacks

Thankfully, there are ways in which firms protect themselves from IoT Security risks. Using penetration testing (pen testing), a simulated attack on your device, you can identify vulnerabilities and fix them before an actual attack hit. Pen testing will search for a range of vulnerabilities, ranging from but not limited to,

1. Weak passwords: passwords that can be guessed or opened through trial and error.
2. Hardcoded passwords: Public passwords that cannot be changed, such as firmware backdoors and client software.  
3. Network services: This helps the devices on the network to communicate and share information. 
4. Ecosystem Interfaces: Authentication, encryption issues, and input/output filtering problems arising from the device’s connections. These could be the internet, the backend API, the cloud, or other devices.
5. Updates: The ability to receive and apply updates to firmware, security, and provide warnings for security changes. 
6. Components: Insecure or outdated components such as software, libraries, customization, third-party apps, etc.  
7. Privacy: Data that can be leaked due to a device on the network not being configured with the proper controls.
8. Data Security: Data encryption and access control during storage, transit, and processing to prevent hijacks between connections. 
9. Default Settings: Insecure default settings that might still be on the device.
10. Physical Hardening: Physical hardening measures to prevent hackers from scoping devices or taking local control of devices. 

Your business must be secure and Pen testing is a great way of identifying these vulnerabilities, which you can then rectify.

Here's how firms can go about it. 

• Identify Devices on The Network - The first step to protecting yourself is to identify which devices are actually on the network. As the network gets bigger, it can be harder to keep track of the devices. Don’t hesitate to pull back, take stock, and remove devices you don’t think need to be on the network.
• Implement Strong Passwords - Without saying, this is the single most important tip. Always ensure your password is not something related to your personal information, such as your full name. Vary your password with numbers and symbols. And don’t use the same password everywhere!
• Download The Latest Security Updates - As attacks increase, so does the defines. Many manufacturers release new updates that patch IoT vulnerabilities. Staying up to date can prevent older attacks from getting through.
• Install Firewalls - Firewalls will prevent unauthorized access through the network. Intrusion detection systems/intrusion prevention systems (IDS/IPS) should be run to monitor and analyse network traffic. Firewalls also have the added benefit of warning you of unauthorized access. This can be the first sign of a breach in security.

IoT has a lot of potential for making human life convenient and efficient. However, it is advisable to take your time with implementing new technologies, make sure you have all the risks covered.

Rigorous testing should be your motto before introducing anything new to your business. Security should be your main priority.
