Microchip Technology has released its CryptoAutomotive security IC, the TrustAnchor100 (TA100). The cryptographic companion device supports in-vehicle network security solutions such as secure boot, firmware update and message authentication, including Controller Area Network (CAN) MAC at bus speed.
“The TrustAnchor100 provides relief for automotive Tier 1s and OEMs when upgrading thousands of ECUs with security,” said Nuri Dagdeviren, vice president of Microchip’s secure products group. “Combining the TA100 and an integrated software stack provides production-ready software for our customers, enabling them to easily add security to any automotive module.”
The TA100 provides an alternative in-vehicle network architecture implementation for secure boot and message authentication — and has already been approved by multiple OEMs around the world as a solution for EVITA Medium and EVITA Full HSM requirements. Its feature set was designed based on a careful review of several prominent OEM cyber security specifications to help facilitate a Tier 1’s pursuit of OEM Part Production Approval (PPAP).
Additionally, Microchip offers security specifications and Request for Quote (RFQ) review services to assist Tier 1s in developing educated responses, improving their project award success rate. 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 — reducing risk, cost and time to market.
The device is confirmed with high resistance to attack through intensive third-party vulnerability assessments. It is AEC-Q100 Automotive Grade-1 qualified, FIPS 140-2 CMVP Security Level 2 rated and Physical Key Protection Level 3 certified, and it has achieved the highest possible vulnerability assessment rating of Joint Interpretation Library (JIL) High.
Also, the TA100 provides software components like AUTOSAR drivers, MCALs and Microchip’s CryptoAuthentication library that allow a seamless integration into the industry-standard operating system, AUTOSAR, or customized software stacks for crypto functions.
