The story so far
Google DeepMind used AlphaProof Code to formally verify selected cryptographic guarantees in the compiled code underlying the Signal protocol. The four-week proof of concept generated more than six million lines of Lean proofs, which Lean checked automatically; human experts reviewed every specification and examined the roughly one percent of the codebase flagged for a second look. The work found no new vulnerabilities in the portions examined. Tests using two previously fixed bugs produced machine-checked proofs that the older, buggy versions were insecure. DeepMind is releasing its specification and proof to support further formal verification work.
