Google DeepMind's AlphaProof Code formally verifies parts of the Signal protocol and finds no new flaws

1 fonte(s) · 1 atualização(ões) · publicado 10/11/2026 02:01 · coletado há 1 hora

Google DeepMind used a new AI framework, AlphaProof Code, to formally verify portions of the Signal protocol, the cryptography that also protects messages on Google Messages and WhatsApp. The four-week proof-of-concept found no new vulnerabilities in the parts it examined. Run against older Signal versions with known, long-fixed flaws, the tool identified them and showed those builds could not be formally verified. The scope was limited: the entire Signal mobile app was not verified, and the researchers present the work as one milestone toward scaling AI-assisted formal verification. DeepMind is releasing the specification and proof to support other verification work, and stresses a human-AI collaboration model with human review at key junctures.

Detalhes técnicos

  • Scope: only selected portions of the Signal protocol were analysed, not the full Signal mobile application.
  • Results: no new flaws in the examined portions; the tool correctly flagged older vulnerable versions as failing verification.
  • Prior work: earlier formal verification by the Signal Foundation gave the team a head start.
  • Cost: the analysis was run free of charge as research; Google did not disclose its cost or any plans for a commercial product.

Remediação

No patch or configuration change is required: the article reports no new vulnerability and names no CVE. The search did not locate DeepMind's or the Signal Foundation's own publication of this work, so the specification and proof should be checked on their official channels before use.
