Google DeepMind's AI Tool Formally Verifies Signal Encryption Protocol

Google DeepMind researchers used an AI tool to formally verify that the Signal encryption protocol, widely used for private messaging, works as intended. The team says its longer-term goal is to apply the same kind of verification to "all the software of the world."

Why it matters: It shows AI-assisted formal verification can prove security properties of real-world production code, a capability that could reshape how teams validate critical software.
