Round 3 of the NIST additional signatures process announced! 🎉 And SQIsign is part of it!! ⛷️⛷️

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

Isogeny-based signatures have consistently had a breakthrough every two years! Let's see what 2026 will bring... (Well, except for SQIsignHD that came a year too late, but that's probably because of Covid)

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

Next week @lucianomaino.bsky.social and I will teach a week-long course on SQIsign at the University of Trento. The course will be both in-person and online: if you're interested, you can tune in Monday morning at 10:30 at unitn.zoom.us/j/88902079708 (details and full schedule in the image below)

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.

Where (in presence): Department of Mathematics, University of Trento (IT)
Via Sommarive, 5, 38123, Trento
(online): https://unitn.zoom.us/j/88902079708 (Passcode: 532383)
When: From May 19, 2025 to May 28, 2025

Great talks today about group actions at the Swissogeny Day by Lorenz Panny and Ryan Rueger! We’re planning to host the next Swissogeny Day in the summer, if you’d like to attend, reach out!

When GitHub is down less than a week before the NIST Round 2 deadline…

Committed my first mistake: I ordered coffee with my breakfast and the guy seemed a bit disgusted I wanted it *with* my breakfast and not after

Ready* and excited for this asiacrypt 🎉 First time in Kolkata and in India, if anyone has good tips on things to do, see, and eat, send them my way! * that is, slides apart
