Google DeepMind uses AI to formally verify Signal protocol security

Google DeepMind has utilized a new AI framework, AlphaProof Code, to formally verify the security of the Signal protocol. This landmark achievement provides independent validation for the cryptography protecting communications on platforms like Signal, WhatsApp, and Google Messages. While the AI-driven formal verification process significantly reduces the time required compared to traditional methods, researchers acknowledge that scaling this capability to secure all software globally remains a long-term goal.
