A New AI Tool From Google DeepMind Proved the Signal Protocol Is Secure

Google DeepMind researchers, working with humans and AI agents, formally verified key parts of the Signal encryption protocol, including its post-quantum handshake and Triple Ratchet, according to WIRED, The Register, and Ars Technica. Ars Technica describes the four-week project as a sign that AI could make formal verification far more practical, and WIRED reports the researchers' stated stretch goal is to apply the same approach to "all the software of the world."
