Forscher*innen von Google DeepMind haben mithilfe von KI-Agenten wichtige Sicherheitseigenschaften des Codes hinter dem Signal-Protokoll mathematisch \u00fcberpr\u00fcft. Das Protokoll sch\u00fctzt Milliarden privater Unterhaltungen in Apps wie Signal, WhatsApp und Google Messages.<\/strong><\/p>\n\n\n\n

Die Forscher*innen setzten AlphaProof Code ein.<\/a>, ein agentenbasiertes Framework mit mehreren gro\u00dfen Sprachmodellen (LLMs), das die Aufgaben der formalen Verifikation \u00e4hnlich wie ein Forschungsteam aufteilt: Menschliche Expert*innen arbeiten dabei mit KI zusammen, um zu entscheiden, was<\/em> bewiesen werden muss, w\u00e4hrend eine Gruppe von KI-Agenten daran arbeitet, die entsprechenden Beweise zu erbringen.<\/p>\n\n\n\n

In just four weeks, the AI agents generated and checked millions of lines of mathematical proofs, demonstrating that key security properties of the Signal Protocol hold.<\/p>\n\n\n\n

To test its ability to detect vulnerabilities, researchers deliberately reintroduced two previously fixed bugs into an isolated version of Signal’s code. AlphaProof Code successfully identified both issues and generated machine-checked proofs showing that the modified code was insecure.<\/p>\n\n\n\n

Signal’s Chief Technology Officer commented<\/a> on the research:<\/p>\n\n\n\n

\u201cWhile prior formal verification focused on smaller portions of the code, Google DeepMind’s approach enables significant expansion. Using AI agents to translate live code into valid Lean theorems is a major breakthrough. As AI-driven security threats grow, rigorously verifying the Signal protocol implementation gives us even greater confidence in our code’s privacy guarantees\u201d.<\/p>\n\n\n\n

While the Signal Protocol already has been extensively assessed by security experts, AlphaProof Code adds another layer of assurance. This marks an important step towards making secure communication even more reliable and shows how AI can help strengthen the security of critical software.<\/p>\n\n\n\n
