For TPM 1.2, the answer is easy. There is no exposed AES or TDES, or any symmetric algorithm. For TPM 2.0, I don't see any direct compare. However, there are some smart people on the TPM work group. If you're a member, join us and ask. ~~ For your specific case, what does "some encrypted secret" mean? Is it a loadable object wrapped with "some symmetric key"? Are -1 and -2 in the clear inside the TPM? Are they encrypted identically, same key and IV? The question is not clear enough. My thought is that, e.g., if -1 and -2 are really identical decrypted secrets inside the TPM, and they can be loaded as HMAC or symmetric keys, then you can indirectly compare them. HMAC or encrypt some data. If the results are equal, the keys are equal. ------------------------------------------------------------------------------ Site24x7 APM Insight: Get Deep Visibility into Application Performance APM + Mobile APM + RUM: Monitor 3 App instances at just $35/Month Monitor end-to-end web transactions and take corrective actions now Troubleshoot faster and improve end-user experience.
