Hi users,
I am planning to design and implement an attestation protocol
with elliptic curve properties. And I decide to use ecc algorithm to
generate attestation keys for signing pcr values instead of rsa
algorithm. Here is my problem.
First, I'm not quite sure it is feasible because of lacking use
case about signing pcr values with ecc keys.
Secondly, if feasible, the generation parameter of ecc keys(such
as elliptic curve formula 、generator )?
I am looking forward to your kindly reply. Thank you!
Trousers is for TPM 1.2 and TPM 1.2 does not support elliptic curve
algorithms.
TPM 2.0 does support elliptic curve.
This TSS supports TPM 2.0 and has a lot of sample code and command line
tools.

This project implements the entire attestation protocol (attestation
signing key enrollment and the quote PCR signing) for elliptic curve.
It has been tested with 3 hardware TPM vendor parts.

A software TPM useful for debugging is here:
