Microchip has released the TrustAnchor100 (TA100) CryptoAutomotive Security IC with pre-programmed security features to simplify automotive network security. The new cryptographic companion device provides OEMs and module suppliers with a simplified path to automotive network security, thereby reducing costs and time to market. The TA100 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 single-chip dual-core hardware security module (HSM) devices available in the market require OEMs and module suppliers to re-architect their application software to integrate security which involves additional effort and increases risks of security holes. Overcoming these barriers, TA100 is provisioned with unique asymmetric key-pairs and associated x.509 and provides an alternative in-vehicle network architecture implementation for secure boot and message authentication.
The device is AEC-Q100 Automotive Grade-1 qualified, FIPS 140-2 CMVP Security Level 2 rated, and Physical Key Protection Level 3 certified. Moreover, it has the highest possible vulnerability assessment rating of the Joint Interpretation Library (JIL) High. Other than this, 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.
The TA100 8-pin SOIC and TA100 14-pin SOIC socket boards are available from the company website with the price range starting at $1.50 in 10,000-unit quantities.
