All papers should publish their code. Help realize this by becoming an artifact reviewer at NDSS'26, apply here: docs.google.com/forms/d/e/1F...
You'll review artifacts of accepted papers. We especially encourage junior/senior PhD students & PostDocs to help. Distinguished reviews will get awards!

Wednesday, May 7, 14:30-16:00 (Room TBD): Cryptography in a Changing World: Navigating Geopolitical Uncertainty and Security Risks Join us to discuss what we as a community can and should do in light of a dramatically changing political landscape, both domestically for some of us and internationally for all of us. We don't have ideas to pitch to you, but we think it will be useful to meet and to start a discussion. For more information: Martin Albrecht and Kenny Paterson.
Together with @kennyog.bsky.social we're organising a meeting at Eurocrypt to discuss how the, let's say, "dramatically changing political landscape" affects cryptography and our community, both domestically in some countries but also internationally eurocrypt.iacr.org/2025/communi...

Finally, a state-of-the-art version of CTIDH! That is, deterministic and a prime of 2048 bits. We introduce a new batching strategy we call "wombats", making dCTIDH five times faster than deterministic CSIDH. Surprisingly, it even beats "non-deterministic" CTIDH.
