Isogeny-based cryptography is famous for its short key size. As one of the most compact
digital signatures, SQIsign (Short Quaternion and Isogeny Signature) is attractive among …

Isogeny-based cryptography is cryptographic schemes whose security is based on the
hardness of a mathematical problem called the isogeny problem, and is attracting attention …

Abstract In 2023, Basso, Maino, and Pope proposed FESTA (Fast Encryption from
Supersingular Torsion Attacks), an isogeny-based public-key encryption (PKE) protocol that …

The threat of quantum computing has spurred research into post-quantum cryptography.
SQIsign, a candidate submitted to the standardization process of the National Institute of …

SQIsign is a post-quantum signature scheme based on isogenies and quaternion algebras.
It was recently submitted to the NIST call for additional post-quantum signatures. For this, a …

This work is a study about the post-quantum signature scheme SQISign, one of the
candidates in the NIST Post-Quantum Cryptography Standardization contest. The SQISign …
