DeepMind's AI proved Signal's code is mathematically secure
Google DeepMind just introduced AlphaProof Code, an agentic framework that formally verified Signal's live cryptographic code in four weeks. Powered by Gemini, the agents generated over six million lines of Lean proofs and flagged just 1% for human review. Why it matters: it automates what once took elite security teams years, proving real-world software flaw-free at mathematical depth.
