    According to Rokubun — a Spanish company that designs accurate and scalable navigation solutions based on GNSS — released a library solution for decoding and processing Galileo Open Service Navigation Message Authentication (OSNMA) for embedded platforms.

    The solution is part of the Horizon Europe BANSHEE project, for which Rokubun served as the coordinating, is EU-funded, and is supported by the European Union Agency for the Space Programme (EUSPA). The goal of the project was to develop a hybrid technology that combines Wi-Fi ranging and satellite navigation (including the Galileo OSNMA) to allow for accurate and seamless indoor-outdoor navigation.

    The upcoming Galileo OSNMA will provide authenticated navigation data message against data-level spoofing attacks. By delivering data authentication, the free-to-use Galileo OSNMA assures users that the received Galileo navigation message comes from the system itself and has not been modified by, for example, a spoofing attack.

    To address this risk, Rokubun’s library enables the Galileo OSNMA in embedded GNSS solutions. The cross-platform, small-footprint library has undergone extensive testing using official EUSPA test vectors, and all OSNMA algorithms have been validated in real conditions at the European Commission’s Galileo testing facilities located at the Joint Research Centre in Ispra, Italy.

    The library is organized to be portable, requiring only a working assembler and C compiler that supports ISO C99. To ensure optimal performance and validate user-specific enhancements, such as the utilization of cryptographic accelerators or other system-on-chip/microcontroller specific resources, Rokubun has implemented a hardware-in-the-loop continuous integration/deployment setup.

    This setup continuously tests the library against several reference MCU targets, assessing its performance and guaranteeing its reliability.

    STMicroelectronics (ST) has launched a new flagship SPC58 H Line as part of its Chorus series of automotive microcontrollers (MCUs).

    The new line can run multiple applications concurrently to allow more flexible and cost-effective vehicle electronics architectures.

    The SPC58 H line has three high-performance processor cores, more than 1.2MB RAM and powerful on-chip peripherals, the company said.

    As critical vehicle powertrain, body, chassis and infotainment features increasingly become defined by software, securely delivering updates such as fixes and option packs over the air (OTA) enhances cost efficiency and customer convenience, the company said.

    With high security and large on-chip code storage, ST’s Chorus automotive microcontroller is a gateway/domain-controller chip capable of handling major OTA updates securely.

    Two independent Ethernet ports provide high-speed connectivity between multiple Chorus chips throughout the vehicle and enable responsive in-vehicle diagnostics. Also featuring 16 CAN-FD and 24 LINFlex interfaces, Chorus can act as a gateway for multiple ECUs (electronic control units) and support smart-gateway functionality via 2 Ethernet interfaces also on-chip.

    “The way carmakers create, configure, deploy and maintain new vehicles is changing, as software-defined functionality makes advanced features, flexibility and convenience ever more widely accessible,” said Luca Rodeschini, microcontroller business unit director at STMicroelectronics. “Our latest and highest-performing Chorus microcontroller, being OTA-ready and with dual Ethernet ports up to Gigabit speeds, creates a state-of-the-art platform for seamless, safe and secure in-car connectivity and control.”

    To protect connected-car functionalities and allow OTA updates to be applied safely, the new Chorus chip contains a Hardware Security Module capable of asymmetric cryptography. Being EVITA Full compliant, it implements industry-leading attack prevention, detection and containment techniques.

    Some customers have received samples of the SPC58 Chorus H Line microcontrollers in the next generation of smart gateways and central body modules, and are also evaluating the devices for battery-management units and ADAS safety controllers.
