Abstract

A mechanism is described for facilitating unified accelerator for classical and post-quantum digital signature schemes in computing environments. A method includes unifying classical cryptography and post-quantum cryptography through a unified hardware accelerator hosted by a trusted platform of the computing device. The method may further include facilitating unification of a first finite state machine associated with the classical cryptography and a second finite state machine associated with the post-quantum cryptography though one or more of a single the hash engine, a set of register file banks, and a modular exponentiation engine.
