The secret attestation scheme is a method for preserving the privacy of users providing authentication of a Trusted Hardware Platform (TPM). A TPM can prove to a remote party that it is a valid TPM without revealing its identity. In the DAA scheme, a TPM can be revoked only if the DAA private key in the hardware has been extracted and published widely so that verifiers obtain the corrupted private key. This scheme allows each user generating the signature to decide or not the signature should be linkable to another signature.
