Automotive Processors Thwart Cyber Threats

STMicroelectronics’ latest automotive processors integrate a dedicated security module. The Telemaco3P telematics and connectivity processors (STA1385 and its variants) are reportedly the first automotive microprocessors to integrate a powerful, dedicated, isolated Hardware Security Module (HSM), which acts like an independent security guard to watch data exchanges and encrypt and authenticate messages. The HSM securely checks the authenticity of received messages and any external devices that try to connect and protects against eavesdropping.

 

The processors boast a +105°C maximum temperature rating. In addition to implementing state-of-the-art security techniques, including symmetric and asymmetric cryptography, the HSM also runs software-security algorithms, giving extra freedom for the main high-performance CPU to host more sophisticated applications.

 

Integrated Controller Area Network with Flexible Data rate (CAN FD), Gigabit Ethernet, and 100Mbit/s Secure Digital I/O (SDIO) interfaces allow the Telemaco3P Family to be used as communication gateways throughout the vehicle, for linking infotainment systems, or Electronic Control Units (ECUs) connected to the CAN bus like door controllers, engine or transmission management systems, or body electronics. Essential power-management circuitry is also integrated, which simplifies design, aids miniaturization, and saves bill-of-materials costs.

 

The STA1385 is designed to comply with the automotive functional-safety standard ISO 26261, up to safety integrity level B (ASIL-B), and meet the AUTOSAR specification for protected communication across the CAN bus. Telemaco3P devices can run POSIX-compliant operating systems, giving users flexibility to choose the optimum OS for a variety of intended use cases.

 

Engineering samples of the STA1385 are available to lead partners now and full production is scheduled for mid-2018. For more specs, an STA1385 datasheet is available. For further information, contact STMicroelectronics, Burlington, MA. 781-861-2650
