The TPM library specification states that the TPM must comply with NIST SP800-90 A.

https://trustedcomputinggroup.org/membership/certification/tpm-certified-products/

shows that the TPMs get third party certification, Common Criteria EAL 4+.

While it's theoretically possible that an attacker could compromise
both the TPM vendors and the evaluation agencies, we do have EAL 4+ assurance against both 1 and 2.

How TPM RNG is guaranteed to protect against both 1 and 2?
