wolfSSL has tested and provides support for a range of public key cryptographic algorithms on the Microchip Trust Anchor (TA100) – Automotive Grade security IC. This includes RSA with 2048-bit key size as well as ECC with 256 key size, supporting both NIST Prime and Brainpool curves. It’s worth noting that the TA100 is a more recent addition compared to the previously supported ATECC508 or ATECC608. To enable this specific configuration, you can use either the Autoconf option by running “./configure –enable-microchip=100” or set the preprocessor define CFLAGS=”-DWOLFSSL_MICROCHIP_AT100″.
The TA100 is a secure element from Microchip portfolio of CryptoAutomotive™ security ICs.The module offers various security features such as code authentication (secure boot), MAC generation for message authentication, support for secure firmware updates, authentication for Qi 1.3 wireless charging, and multiple key management protocols including TLS. It is a highly secure solution offering features such as key agreement and sign-verify authentication. It supports various asymmetric, symmetric, and hashing security protocols to ensure robust protection.
The TA100 is compatible with a range of microprocessors (MPUs) and microcontrollers (MCUs), including our AVR® and ARM® processor-based MCUs and MPUs. Its versatility allows for seamless integration into different system architectures.
