Microchip Trust Anchor TA100

FIPS 140-2 certificate #4421 · Microchip Technology Inc · data as of 2026-10-09

Microchip Trust Anchor TA100, from Microchip Technology Inc, holds FIPS 140-2 certificate #4421 at overall level 2. The validation is historical: agencies may keep the module in existing systems but not buy it new. Below are its algorithm certificates, its validation history, and the list moves this tracker has observed, which NIST does not date.

Historical. Moved to historical list due to sunsetting. Federal agencies may reference historical validations for existing systems only, not for new procurement. Observed moving to historical on 2026-09-22. It was one of the last FIPS 140-2 certificates, all moved at the 140-2 sunset on 2026-09-21.
Caveat: The module generates cryptographic keys whose strengths are modified by available entropy. When installed, initialized and configured as specified in Section 5 of the Security Policy

Module description

Quoted from the NIST CMVP entry for this certificate.

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.
