ecdaa

A library of ECDAA with TPM (Trusted Platform Module).

ECDAA is a privacy-enhancing cryptographic primitive. ECDAA prevents tracking but attests that the computer is in some group.

The central use-case of ECDAA is proving the manufacturer of computers for security reasons (e.g. prove how secret keys are stored) but the end-user is concerned about tracking.

This library mainly supports the FIDO ECDAA, but it uses TPM2_Sign instead of TPM2_Certify for extensibility.
