Attending ArcticCrypt 2025

24 July 2025

From July 6th to 11th, the QuSAC group attended the second edition of ArcticCrypt – the world’s northernmost cryptography conference – at the Radisson Blu Polar Hotel in Longyearbyen, Svalbard. The conference covered a wide range of topics, including multiple talks on isogeny-based cryptography, cryptanalysis, secure multi-party computation and practical applications of cryptography.

Prof. Slamanig was invited to chair the conference's session "Mathematical Aspects of Cryptography", and Sebastian Spindler presented the paper “More Efficient Isogeny Proofs of Knowledge via Canonical Modular Polynomials”, which originated from a collaboration of the QuSAC group with CODE colleague Sören Kleine.

A preprint of the group's paper, which will also be presented at the CRYPTO 2025 conference in August, can be found in the IACR Cryptology ePrint Archive.

3 Papers accepted at ASIACRYPT 2025

This year, three papers by the QUSAC group were accepted at the renowned ASIACRYPT conference. The 31st edition of the International Conference on the Theory and Application of Cryptology and Information Security – ASIACRYPT 2025 – will take place this year from December 8-12 in Melbourne, Australia. Below are brief summaries of the three accepted papers:

BIRS workshop “Isogeny Graphs in Cryptography”

From August 3rd to 8th, Sebastian Spindler attended the workshop “Isogeny Graphs in Cryptography” in Canada. In his lightning talk “On the diameter of the supersingular ℓ-isogeny graph” Sebastian presented part of his new preprint “Exploring Kaneko’s bound: On multi-edges, loops and the diameter of the supersingular ℓ-isogeny graph” that he recently published together with Sebastiano Boscardin from the Eindhoven University of Technology.

ACNS 2025 & PrivCrypt 2025

The 23rd International Conference on Applied Cryptography and Network Security (ACNS 2025) was held in Munich, Germany, at the Munich Urban Co-Lab on 23–26 June 2025. In this year’s edition, Prof. Slamanig served as the Poster Chair of the conference.

CrypTO Conference

A researcher from the QuSAC lab (Marzio Mula) attended the CrypTO Conference in Turin, held on May 22–23, 2025. He presented the talk “Representing isogenies via (classical, canonical, Atkin...) modular polynomials”, based on joint work with the QuSAC group, Marc Houben, and Sören Kleine.

EUROCRYPT 2025 and Inivted Talk at CTB'25

From May 4th to 8th, the 44th edition of Eurocrypt — one of the world’s leading scientific conferences in the field of cryptography took plase at the RIU Hotel in Madrid, Spain. Each year, the event showcases the most significant advances in cryptographic research.

Paper accepted at CRYPTO 2025

The paper "More Efficient Isogeny Proofs of Knowledge via Canonical Modular Polynomials" by the QuSAC group and CODE colleague Sören Kleine has been accepted for publication at the CRYPTO 2025 conference, which will take place in Santa Barbara, USA on August 17-21, 2025.
