The third 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, 9 May 2026 in Rome.

ProTeCS is an affiliated event at Eurocrypt 2026. All participants must be registered through the Eurocrypt website.

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.
