The elliptic curve-based Enhanced Privacy ID (EPID) signature scheme is broadly used for hardware enclave attestation by many platforms that implement Intel Software Guard Extensions (SGX) and other devices. This scheme has also been included in the Trusted Platform Module (TPM) specifications and ISO/IEC standards. However, it is insecure against quantum attackers. While research into quantum-resistant EPID has …
