The Microchip® Trust Anchor (TA100) is a secure element from the Microchip CryptoAutomotive™ portfolio intended for automotive security applications providing support for code authentication (aka secure boot), message authentication via MAC generation, support for trusted firmware updates, multiple key management protocols including TLS and other root-of-trust based operations.  It is typically a companion device to an MCU or MPU on the same board.

The Microchip TA100 integrates  multiple asymmetric, symmetric, and hashing security protocols supporting an ultra-secure method for key agreement, sign-verify authentication for automotive in-vehicle networking applications.,   Similar to all Microchip CryptoAutomotive™ products, the new TA100 employs ultra-secure hardware-based cryptographic key storage and cryptographic countermeasures which eliminate potential backdoors linked to software weaknesses.

The device is agnostic of any microprocessor (MPU) or microcontroller (MCU) and compatible with Microchip AVR/ARM MCUs or MPUs.
