Google DeepMind has used AI to mathematically prove the security of the Signal protocol, a landmark development for cryptography and AI. The AI framework, AlphaProof Code, verified the protocol's key cryptographic guarantees in just four weeks. This analysis serves as further independent validation of the cryptography that protects communications on platforms like Signal, WhatsApp, and Google Messages. The researchers emphasize that their findings are just one milestone in a larger process, and there is still a long way to go before scaling this to all the software of the world.
