TrustAnchor provides simple path to automotive network security

Thu, Nov 12, 2020

Automotive OEMs and their module suppliers can use TrustAnchor to upgrade existing designs to meet security requirements, says Microchip. The cryptographic security IC supports in-vehicle network security solutions such as secure boot, firmware update and message authentication, including controller area network (CAN) MAC at bus speed, says Microchip.

The rise of in-vehicle network connections like Bluetooth and LTE/5G, means convenience but also more vulnerabilities in an automotive system. The TrustAnchor100 (TA100), CryptoAutomotive security IC helps OEMs and their module suppliers to simplify the upgrade of existing designs to meet security requirements for future generations.

To comply with new security specifications, automotive designers have to revise the vehicle’s electronic control units (ECUs) with secure hardware. Using single chip, dual core hardware security module (HSM) devices for this requires OEMs and module suppliers to rework application software to integrate the security element. This can introduce security holes, which can be overcome by third party security software but it will increase development costs.

The TA100 provides an alternative in-vehicle network architecture implementation for secure boot and message authentication. It has been approved by OEMs around the world as a solution for EVITA (e-safety vehicle intrusion protected applications) medium and full HSM requirements. Its feature set was designed following the review of OEM cybersecurity specifications. Microchip also offers security specification and request for quote (RFQ) review services to assist Tier 1s in developing educated responses.

According to Microchip, the TA100 removes the challenges associated with secure code development and provisioning by offering pre-programmed cryptographic internal application code provisioned with unique asymmetric key-pairs and associated x.509 certificates, thereby reducing risk, cost and time to market.

The device has high resistance to attack through intensive third-party vulnerability assessments, says Microchip and is AEC-Q100 Automotive Grade-1-qualified, FIPS 140-2 CMVP Security Level 2-rated and Physical Key Protection Level 3-certified. It has also achieved the highest possible vulnerability assessment rating of Joint Interpretation Library (JIL) High. The TA100 provides software components like AUTOSAR drivers, MCALs and Microchip’s CryptoAuthentication library for seamless integration into AUTOSAR, the industry standard OS, or customised software stacks for crypto functions.

The TA100 offers AUTOSAR-compliant MCAL drivers that can be integrated into an AUTOSAR software stack. A full AUTOSAR reference stack is available, enabling automotive vendors to deploy the latest crypto standards into automotive systems within standard automotive production environments, explains the company. MikroBUS-compatible socket boards are also available.

The TA100 is available in an eight- and 14-pin SOIC packages.

Reference design for ToF lidar supports range finding for precision robotics

Tue, Nov 10, 2020

Light detection and ranging (lidar) is increasingly popular in robotics and industrial proximity sensing where mm range accuracy is required. ON Semiconductor has introduced the a reference design based on its Silicon Photomultiplier (SiPM) technology.

The SiPM direct time of flight (dToF) lidar platform exploits the dToF method, which measures the time it takes for a pulse of light, normally in the near infrared (NIR) wavelength range, to travel to and from an object. This deceptively simple technology can incur challenges, such as high levels of ambient solar light. To determine range accurately, the receiver needs to capture as much of the signal as possible. ON Semiconductor says that the SiPM sensor overcomes the shortfall of traditional photodiodes by providing faster response times and high detection efficiency. The reference platform uses the RB-Series, second generation of SiPM sensors, which deliver improved performance in red and the NIR range.

The reference design includes the NIR laser diode, SiPM sensor and optics, as well as the digital processing necessary to convert the detected signals into elapsed time, and elapsed time into distance. OEMs can adapt it for production of industrial range finding applications.

To accelerate customers’ time to market, ON Semiconductor has made all of the design data for the reference platform available, covering the schematics, BoM, Gerber files, and PCB design files. A PC-based GUI is also accessible, which provides a graphical representation of the measurements over time. The histograms generated provide further evidence of the system’s capabilities in applications such as range finding, collision detection and 3D mapping.

The SiPM dToF lidar platform can detect objects at distances between 100mm and 23m. The design is FDA Class 1 certified and compliant with IEC / EN 60825-1:2014 and 21 CFR 1040.10/ 1040.11 laser safety standards.

ON Semiconductor supplies semiconductor-based solutions, offering a portfolio of energy efficient, power management, analogue, sensors, logic, timing, connectivity, discrete, SoC and custom devices for automotive, communications, computing, consumer, industrial, medical, aerospace and defence applications.

ON Semiconductor operates a network of manufacturing facilities, sales offices and design centres in key markets throughout North America, Europe and the Asia Pacific regions.

EdgeReady provides touchless access control via face recognition

Mon, Nov 09, 2020

Based on its i.MX RT106F crossover microcontroller, NXP offers EdgeReady for the IoT, with a license for facial recognition software to provide touchless access control.

OEMs can use EdgeReady to quickly, easily and inexpensively add vision-based touchless access control, says NXP. The microcontroller and AI/ML-based face recognition software makes possible face recognition with liveness checking using infra red and RGB cameras, flash and SDRAM at a total cost of less than US$10, says the company.

It can be used to implement face recognition for authenticating and operating secure machines, equipment, and access points for hotels, public buildings and homes, for example, doors, locks, amenities, lifts, garage doors and security systems.

The infra red camera operates with a visible light (RGB) camera to distinguish a real person from a photograph. This prevents unauthorised access without the need for an expensive 3D structured light or time of flight (ToF) camera, says NXP.

It responds in 0.5 seconds. Face detection, quality check, liveness detection and face recognition are all conducted in less than 500 milliseconds at the microcontroller-based edge instead of the cloud, to make access systems convenient.

It also enhances data privacy by allowing all personal biometric data to remain on the device at the edge. This helps address privacy regulations as well as the concerns of consumers to protect data.

The battery life is maximised with a fast microcontroller boot up time. The device enters power saving mode when not in use. A fast recognition time is combined with the microcontrollers low active power, says NXP, to further meet low power system requirements.

A customisable smartphone or PC application can enable biometric models to be sent to remote locks and other devices for controlled access in hospitality, smart building and smart home applications.

NXP also offers the i.MX RT106F-based development kit (SLN-VIZNAS-IOT) to accelerate time to market. It contains all the software and hardware information to complete designs in as little as six months, says NXP. In addition to negating integration and coding, the NXP EdgeReady IoT for secure face recognition based on the i.MX RT106F development kit includes schematics, bill of materials (BoM), board layout and ready-to-use face biometric registration application.

The SLN-VIZNAS-IOT secure face recognition development kit is available now from NXP and authorised distributors.

The i.MX RT106F microcontroller is available now. It includes a license to use the NXP face recognition SDK. The device is available in consumer and industrial temperature grades.
