DeepMind formally verifies real-world Signal protocol implementation at machine-code level with AlphaProof Code
swarat · x · 2026-11-10
A Google DeepMind team announced a major milestone in software engineering and cybersecurity: formally verifying a real-world implementation of the Signal cryptographic protocol at the machine-code level, using AlphaProof Code, their new AI framework for formal specification and verification. The paper, Lean proof code, and DeepMind blog post are public. The author reflects on starting formal verification research 20+ years ago, inspired by Dijkstra's vision of programming backed by mathematical theorems.
