Join us tomorrow for ProTeCS, one of Eurocrypt’s affiliated events! We are thankful to have two amazing invited speakers, Bart Mennink and Mike Rosulek! We are also happy to have seven contributed talks from the community. Check out our full program here: protecs-workshop.gitlab.io/program

The Cryptographic Applications Workshop (CAW) happens this Sunday in Rome! Just a reminder that if you're not coming to Rome you can still attend remotely. Just register here: forms.gle/2JZ7hLs8diQM... before May 8. See caw.cryptanalysis.fun for more infos and our program.

I'm looking for a PhD student to work with me on formal verification for cryptographic protocols. This is a 4-year position at VU Amsterdam, co-supervised with Kristina Sojakova. Send me an email if you want to know more!

I am very excited that our work on secure cloud storage is now online. A big shoutout also to my co-author @jonasjanneck.bsky.social who will present the results at Eurocrypt’26!

📢📢📢 𝐌𝐚𝐆𝐈𝐂 𝟐𝟎𝟐𝟔 𝐌𝐚𝐫𝐜𝐡𝐞 𝐖𝐨𝐫𝐤𝐬𝐡𝐨𝐩 𝐨𝐧 𝐆𝐫𝐨𝐮𝐩 𝐀𝐜𝐭𝐢𝐨𝐧𝐬 𝐢𝐧 𝐂𝐫𝐲𝐩𝐭𝐨𝐠𝐫𝐚𝐩𝐡𝐲 In May 5-8, let's all gather together to speak about Group Actions! Early registration until March 8! Organized with Marco Baldi, @bsky.defeo.lu, @giacomoborin.bsky.social, @andreavbasso.bsky.social magic-workshop.github.io

Happy to announce that Bird of Prey is accepted at EC’26 🛸✍️🎉 eprint.iacr.org/2025/1844 The paper presents three signature combiners for PQC migration preserving strong unforgeability. They capture all broadly used classical schemes and can be used with *any* PQ signature in a black-box way!

I am very happy to announce that thanks to the hard work of many people (The "MIKE Team"), we now have a working implementation in SageMath of MIKE (Module Isogeny Key Exchange).

📢 We have extended the deadline for our EC workshop to *Monday AoE*! Submit your talk proposal on any topic related to cryptographic proofs and proof techniques 🤓 Take the opportunity to advertise your ongoing, submitted or published work, or to share other insights related to security proofs

Remember to submit your ProTeCS talk. The deadline is on Thursday!

Planning your trip to Eurocrypt or looking for an excuse to still go? The reviewers did not appreciate your too involved or too elegant proofs? Consider submitting a talk to ProTeCS (protecs-workshop.gitlab.io), an affiliated event of EC, where we celebrate proofs as independent objects of study!

New paper out! 🎉 We translate the algebraic group model to the (generic) isogeny setting, generalising previous results that were limited to oriented isogenies (we show that any result that holds in the AGAM also holds in the AIM). Using this model, we obtain two important results:

The Algebraic Isogeny Model: A General Model with Applications to SQIsign and Key Exchanges (Marius A. Aardal, Andrea Basso, Doreen Riepel) ia.cr/2026/032

ABE Cubed: Advanced Benchmarking Extensions for ABE Squared (Sven Argo, Marloes Venema, Doreen Riepel, Tim Güneysu, Diego F. Aranha) ia.cr/2025/1230

The SQIparty starts on Monday, but it's still time to register! We prepared an exciting program for you with a balanced mix of talks, coding sprints, skillshares and other activities! www.cig.udl.cat/SQIparty2025... See you in Lleida!

Really excited to share the Decrypting Diversity Summit happening in Montpellier, France from 17-20 June! The goal of the summit is to promote diversity, inclusivity, and gender equality within the cryptography community. For more info: decryptingdiversity.com

Interested in formal verification for cryptography? But not sure where to start? If you are coming to Eurocrypt, consider joining us for CAPS, the workshop on Computer-Aided Proofs of Security! caps-workshop.com

We have extended the submission deadline for the International Workshop on Foundations and Applications of Privacy-Enhancing Cryptography (PrivCrypt) by two weeks to April 4, 2025, AoE. Please help spread the word and consider submitting your work to join us in Munich in Summer 😎

Join our Applied Crypto group at FAU in Nürnberg as a PhD student or spread the word: we're hiring. Our work covers many topics in real-world crypto, especially provable security and privacy of modern messaging protocols 🔐✉️ www.jobs.fau.de/jobs/7-phd-p...

Lattice-Based Updatable Public-Key Encryption for Group Messaging (Joël Alwen, Georg Fuchsbauer, Marta Mularczyk, Doreen Riepel) ia.cr/2025/365

The list of accepted papers and the (preliminary) program for PKC 2025 are now available online: pkc.iacr.org/2025/program... We are also delighted to announce that Jesper Buus Nielsen has accepted our invitation to give an invited talk at PKC 2025! See you at PKC 2025!

Come join us at the SPIQE workshop in Munich in June! spiqe-workshop.github.io - we are now open for paper submissions and talk proposals on all aspects of secure protocol implementation for the post-quantum era.
