CRYPTO : Antonin Leroux (Inria Saclay) : SQISign: Compact Post-Quantum Signature from Quaternions and Isogenies
Bâtiment Descartes, salle 301We introduce a new signature scheme, SQISign, (for Short Quaternion and Isogeny Signature) from isogeny graphs of supersingular elliptic curves. The signature scheme is derived from a new one-round, high soundness, interactive identification protocol. Targeting the post-quantum NIST-1 level of
