A New AI Tool From Google DeepMind Proved the Signal Protocol Is Secure
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.
AIWhy it matters.
The article explains which Signal guarantees were checked, what the method found in old vulnerable versions, and where its scope still falls short.
