Swissogeny Day

The swiss isogeny day is a recurring meetup of cryptographers working on isogeny-based cryptography in and around Switzerland.

In the past we have had attendees from ENS de Lyon, EPFL, ETH Zurich, Ethereum Foundation, IBM Research, Technische Universität München, Université Côte D'Azur, Universität der Bundeswehr München, Universität Konstanz, and UZH.

Next event

The next Swissogeny Day will take place on Thursday June 26, 2025 in room C42 in the IFW building at ETH Zurich.
