Dagstuhl Seminar "Privacy-Preserving Authentication"

27 April 2026

Prof. Slamanig recently participated in the Dagstuhl Seminar titled "Privacy-Preserving Authentication," held from April 19 to April 24, 2026. Dagstuhl seminars are held at Schloss Dagstuhl – Leibniz-Zentrum für Informatik and are invitation-based research workshop where around 30–40 scientists spend a week discussing a focused topic in computer science.

The seminar focused on privacy-preserving authentication, addressing current research challenges in enabling secure identity verification while minimizing the disclosure of personal information. Key topics included the design of advanced cryptographic mechanisms such as anonymous credentials, zero-knowledge proofs, blind signatures, and oblivious pseudorandom functions (OPRFs), as well as techniques for selective disclosure and revocation. The seminar also examined the integration of these building blocks into real-world systems, with particular attention to emerging digital identity frameworks such as European Digital Identity (EUDI) wallets.

Aktuelles

PQCrypto 2026

From April 14th to April 16th Sebastian Spindler attended the 17th edition of the PQCrypto conference, which was held in Saint-Malo. The conference program covered a wide range of recent advances in post quantum cryptography, such as new signature scheme constructions, the cryptanalysis of both various security assumptions and some concrete constructions, as well as talks about quantum security and the general design of protocols in view of the ongoing transition to post quantum cryptography.

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.
