SQIparty2025 in Lleida

9 May 2025

Last week Sebastian Spindler attended the SQIparty2025, a workshop on isogeny-based cryptography that was held in Lleida, Spain on April 28-30, 2025. Between many interesting talks on SQIsign, higher-dimensional techniques as well as related topics and the more interactive skillshare sessions, the workshop provided the perfect opportunity to learn about and discuss current developments in isogeny-based cryptography, even in the face of the countrywide power outage in Spain.

ZKProof 7 and RWC in Sofia

A researcher from QuSAC (Thomas den Hollander) recently travelled to Sofia to attend ZKProof 7, the leading initiative focusing on the development and standardization of zero-knowledge proofs. There he presented research by the QuSAC group and met other researchers in the area of proof systems and zero-knowledge.

Young Researcher Crypto Seminar

From the 3rd to the 5th of March, Sebastian Spindler and Thomas den Hollander visited the Young Researcher Crypto Seminar (YRCS) in Konstanz. There they both presented recent QuSAC research on proving knowledge of isogenies. They also used the opportunity to meet fellow early career researchers and discuss new developments in cryptology.
