| How PUF Circuitry Protects the IoT
As IoT designs proliferate, security is lagging behind. Shared secrets and public-key cryptography provide some options, but not without their own vulnerabilities. On the other hand, hardware-based security using physically unclonable function (PUF) circuitry strongly protects connected products against invasive attacks. With PUF technology, a cryptographic key is generated only when needed and is never stored on the secure IC. Each chip is unique, much in the way that our DNA provides us with a unique identifier. Even probing the chip impedes the attack by changing its electrical characteristics. Read this blog post to learn how PUF circuitry safeguards IoT designs. CONTINUE READING

Express Logic IoT Platform Gets Thread Certification
Express Logic has announced that its Industrial Grade X-Ware IoT Platform is an official Thread Certified Product, and the only such solution from an independent RTOS provider. Created by the Thread Group, Thread is a reliable, low-power, secure and scalable mesh networking solution that provides a foundation on which any application layer can run.
The X-Ware IoT Platform, powered by Express Logic's high-performance ThreadX RTOS and NetX Duo dual IPv4/IPv6 TCP/IP stack, provides industrial-grade implementations of IPv6 over Low Power Wireless Personal Area Networks (6LoWPAN), Constrained Application Protocol (CoAP) and Datagram Transport Layer Security (DTLS).
According to Express Logic, Thread certification provides more than just protocol compliance. Rather than measuring against single reference implementations, Thread testing validates each device's specification conformance against a blended network comprised of four reference stacks. Compliance to the Thread certification protocols and standards is administered and regulated by UL, a global, independent, safety and certification company with more than a century of expertise in implementing certification solutions and standards.

Chipsets Provide Low Power LoRa Solutions Semtech has announced its next generation LoRa devices and wireless radio frequency (RF) technology (LoRa Technology) chipsets enabling innovative LPWAN use cases for consumers. Addressing the need for cost-effective and reliable sensor-to-cloud connectivity in any type of RF environment, the new features and capabilities will significantly improve the performance and capability of IoT sensor applications that demand ultra-low power, small form factor and long range wireless connectivity with a shortened product development cycle.
The next generation LoRa radios extend Semtech's link budget by 20% with a 50% reduction in receiver current (4.5 mA) and a high power +22 dBm option. This increases the battery life of LoRa-based sensors up to 30%, which reduces the frequency of battery replacement. The extended connectivity range, with the ability to reach deep indoor and outdoor sensor locations, will create new markets as different types of verticals integrate LoRa Technology in their IoT applications including healthcare and pharmaceuticals, media and advertising, logistics/shipping and asset tracking.

Mouser Electronics Inks Distribution Deal with Onion Mouser Electronics has signed a global distribution agreement with Onion, a global provider of integrated wireless microprocessor modules and IoT development kits. Through the agreement, Mouser will distribute the Omega2+ device, kits and accessories. They are ideal for applications such as home automation, coding education, Wi-Fi media servers, robotics and networking.
The Onion product line, available from Mouser Electronics, revolves around the Omega2+ (shown), an easy-to-use, expandable IoT computer with built-in Wi-Fi connectivity, a MicroSD card slot and a powerful 580 MHz MIPS processor. Though just a fraction of the size of other single board computers, the Omega2+ is a full computer with a Linux operating system, 128 MB of DDR2 memory and 32 MB of flash storage. The device also offers 15 general-purpose inputs and outputs (GPIO), two PWM and two UART interfaces.

Processor Empowers Voice-Controlled IoT Devices
To address the convergence of immersive sensory experiences fueled by voice, video and audio demands, NXP Semiconductors has launched the i.MX 8M family of applications processors. The processors combine robust media capabilities on one chip. Voice commands are expected to dominate 50% of all searches in the next two years, increasingly thinner TVs are driving the popularity of sound bars for home automation, and consumers are embracing the IoT for creating more convenient richer sensory-driven experiences. With all that in mind, the NXP i.MX 8M processors address designers' requirements for one platform that combines A/V and machine learning to create connected products that can be controlled via voice command. The chips provide the process technology and edge computing needs to manage and reduce the command and question response time of smart connected devices. The i.MX 8MF is suited for a wide range of residential IoT and device control applications including everything from smart TVs, television subscription services, sound bars and other smart speakers, to streaming media players and DVR/PVR. The processor family is also ideal for managing lighting, thermostats, door locks, home security, smart sprinklers, other systems and devices for a more intuitive and responsive home environment.
