Google DeepMind uses AI to formally verify parts of the Signal protocol
Overview
Google DeepMind researchers used agentic AI and a new framework called AlphaProof Code to formally verify several key cryptographic guarantees of the Signal protocol in four weeks, according to Wired.
The analysis found no new vulnerabilities in the parts examined and correctly flagged known flaws in older Signal versions that had already been fixed.
The researchers say the work covers only part of the protocol and does not verify the entire Signal mobile app. They are releasing the specification and proof.

AIGoogle DeepMind researchers used agentic AI and a new framework called AlphaProof Code to formally verify several key cryptographic guarantees of the Signal protocol in four weeks. The analysis found no new vulnerabilities in the parts examined, and it correctly flagged known, long-fixed flaws in older Signal versions. The researchers say the work covers only part of the protocol and does not verify the entire Signal mobile app, and they are releasing the specification and proof.
