Google DeepMind researchers used their AlphaProof Code agentic AI framework to formally verify key cryptographic guarantees of the Signal protocol, marking a significant milestone for both cryptography validation and AI-assisted formal verification. The proof-of-concept project took four weeks but only covered parts of Signal, not the full app.
Background
Formal verification uses mathematical methods to prove software correctness and security properties. Signal is the leading encrypted messaging platform protecting billions of users worldwide.
