Postdoc researcher on isogeny-based and post-quantum cryptography at IBM Research🇨🇭

Screenshot of email announcement saying: Nine Candidates Advance to the Third Round of the Additional Digital Signatures for the PQC Standardization Process After 18 months of evaluation, NIST has selected nine candidates for the third round of the Additional Digital Signatures for the Post-Quantum Cryptography (PQC) Standardization Process. The advancing digital signature algorithms are: FAEST HAWK MAYO MQOM QR-UOV SDitH SNOVA SQIsign UOV
A timeline of isogeny-based signatures over the years: 2012 - A signature from group actions: First signature from isogenies in the literature 2014 - SIDH: Also proposes an identification protocol 2016 - GPS: First signature from endomorphism ring knowledge 2018 - SeaSign: First signature based on CSIDH 2020 - SQIsign: Compact and “practical" signature from endomorphism ring knowledge 2023 - SQIsignHD: HD representations make SQIsign signing much faster 2024 - SQIsign2D: Significantly improved SQIsign signing and verification
Title of the PhD course: Advances in Cryptography and Codes - Part 1: SQIsign Lecturers: Andrea Basso (IBM Research Zurich, CH), Luciano Maino (University of Bristol, UK) The course in short: The course offers a comprehensive and rigorous introduction to SQIsign, an advanced isogeny-based digital signature scheme designed to resist attacks from quantum computers. The course will present the mathematical foundations on which SQIsign is based and the algorithmic background necessary to understand and evaluate the security of SQIsign and other isogeny-based protocols. Complementing the theoretical material, the course also includes a practical laboratory where students will use SageMath to study and implement various aspects of SQIsign.
