EPID with Efficient Proof of Non-Revocation
Proceedings of the 2022 ACM on Asia Conference on Computer and Communications Security, 2022 EPID systems are anonymous authentication mechanisms which are standardized by ISO/IEC and massively deployed in Intel processors. They are related to the large family of privacy-preserving signatures but differ in that they provide a very pragmatic way of revoking members.
