摘要
In some embodiments, a method and apparatus for enhanced revocation of direct proof and direct anonymous attestation are described. In one embodiment a trusted hardware device verifies that membership of the device within a trusted membership group is not revoked according to a revocation list received with a challenge request from a verifier. Once such verification is performed, the device convinces the verifier of possessing cryptographic information without revealing unique, device identification information of the trusted hardware device or the cryptographic information. In one embodiment, the trusted hardware device computes a digital signature on a message received with the challenge request to the verifier if membership of the anonymous hardware device within a trusted membership group is verified. In one embodiment, the verifier authenticates the digital signature according to a public key of the trusted membership group to enable a trusted member device to remain anonymous to the verifier. Other embodiments are described and claimed.
