Is there a TZ-TPM reference implementation available?

[lyance]

Was looking for a reference to implement a TPM2.0 in an armv7 SoC using TZ. If a TRNG like this is available, was hoping to find one that has most of TPM2.0-specs implemented in TZ.

Any referrals or advices would be appreciated. Thanks!

Hi, TZ-TRNG is a standalone project, which is not included in Arm CPU bundles. TRNG is a kind of hardware (true) random number generator. The true randomness adds up to the security level of TrustZone or other cryptographic systems. The codes here have to work with the TRNG silicon IP provided by Arm.
