Kind: research · Impact: medium

## In brief

- Google DeepMind researchers used an AI tool to formally verify that the Signal Protocol works as intended.
- The researchers' stated stretch goal is to do the same for "all the software of the world."

## Why it matters

Formal verification of a widely used encryption protocol shows that AI-assisted proof tools can check security-critical code, which may matter for how teams verify cryptographic software.
