YRCS 2026

From the 18th until the 20th of March, the Young Researcher Crypto Seminar (YRCS) was held at the Hasso-Plattner-Institut in Potsdam. Researchers from the QuSAC group attended to present and discuss ongoing research. Thomas den Hollander presented the QuSAC group's recent work on proving knowledge of isogenies.

Swissogeny Day 2026

On 20 March 2026, QuSAC researcher Marzio Mula gave a talk at the Swissogeny Day 2026, hosted at IBM Research Zurich. In his talk, “SNARK Magic and Other Tricks for Proving Isogeny Knowledge”, Marzio presented recent work on non-interactive zero-knowledge proofs of knowledge of isogenies. Such proofs are useful to demonstrate the possession or well-formedness of cryptographic public keys, to support multiparty generation of supersingular elliptic curves with unknown endomorphism ring, and as building blocks digital signatures.

MSCA Postdoctoral Fellowship Awarded to Dr. Marzio Mula

We are delighted to announce that QuSAC researcher Dr. Marzio Mula has been awarded a Marie Skłodowska‑Curie Action (MSCA) Postdoctoral Fellowship. Marzio will join the CANARI team at Inria Bordeaux and the Institut de Mathématiques de Bordeaux for a two‑year fellowship with his project IsoPODS (Isogeny‑Based Primitives, Optimisations, and Dynamical Systems).

OIST Visiting Program

From January 13th to January 26th Sebastian Spindler participated in the first two weeks of the OIST Thematic Program “Isogeny-based Cryptography” in Onna (Okinawa, Japan). The mornings started off with many interesting research talks, and afterwards the participants formed smaller groups to brainstorm on various topics in the current landscape of isogeny-based cryptography.

Asiacrypt 2025

From the 8th until the 12th of December, members of the QuSAC group visited Asiacrypt, the largest cryptography conference of Asia. The 2025 edition took place in Melbourne, Australia. It was a valuable opportunity to speak with other researches and learn about recent research. In total, 3 papers accepted at the conference were (co-)authored by members of the QuSAC group.

Swissogeny Day Lausanne

On November 26th Shernyce Duncombe, Marzio Mula and Sebastian Spindler participated in the fourth edition of the Swissogeny Day, which was hosted at the EPFL in Lausanne. The one-day workshop kicked off with research talks on generalized lollipop attacks, an alternative approach to SQIsign incorporating level structures, and an attack on the active security of PEARL-SCALLOP.

Research Visit and Seminar Talks @ INRIA Bordeaux

In November 2025, two researchers from the QuSAC lab, Marzio Mula and Sebastian Spindler, visited the CANARI project-team at Inria Bordeaux and the Institut de Mathématiques de Bordeaux. During their stay, they gave two seminar talks at the Algorithmic Number Theory Seminar (Séminaire de Théorie Algorithmique des Nombres).
