LLM agents that write machine-checked cryptographic proofs in EasyCrypt (arXiv:2607.02847)

We implement the Schnorr proof system in assembler via the Jasmin toolchain, and prove the security (proof-of-knowledge and zero-knowledge) and the absence of leakage through timing side-channels of that implementation in EasyCrypt.

Mastering the Art of EasyCrypt Programming

🔏 VRIL-KEM is a post-quantum Key Encapsulation Mechanism (KEM) built on Module Learning With Errors (M-LWE). It provides a drop-in replacement for classical key exchange in any TLS, SSH, or application-layer protocol — protecting encrypted communications against both classical and quantum adversaries.
