The second Workshop on Proofs and Proof Techniques for Cryptographic Security (ProTeCS) focuses on cryptographic proofs as independent objects of study and will be held on

Saturday, 3 May 2025 in Madrid.

ProTeCS is an affiliated event at Eurocrypt 2025. All participants must be registered through the Eurocrypt website.

Call for Presentations

ProTeCS 2025 will again solicit contributed talks. Please consult the Call for Presentations for details.

Workshop aims

Cryptographic reductions, simulations and security arguments are an important part of evaluating the (in)security of cryptographic algorithms and designs before they are realised—in standards, software and hardware. Despite the rich landscape of techniques used for reasoning about the security of primitives, constructions and interactive protocols, the cryptographic security proofs themselves are often seen as “attached” to the objects they relate to, and rarely studied as independent objects.

ProTeCS celebrates cryptographic proofs as independent objects of study and discussing the techniques that bring such proofs to life in practice, further fostering the growth of the community of proof nerds. In particular, we will focus on discussing coming challenges for cryptographic proof writers, from quantum reductions and simulations, to the need for end-to-end proof techniques that apply all the way from core primitives to high-level security requirements.

In addition to invited talks, we invite the community to submit short presentations.
