She Raised $64M to Build an AI Math Prodigy | Carina Hong, CEO of Axiom

Carina Hong, Founder & CEO of Axiom, discusses building a self-improving AI reasoning engine that combines generation and verification. Starting with formal mathematics, Axiom's system has achieved superhuman results on the notoriously difficult Putnam Exam by leveraging formal languages like Lean to overcome the probabilistic and unverifiable nature of standard LLMs. Hong explores how this technology can solve major bottlenecks in hardware and software verification, code migration, and database consistency, and what it means for the future of mathematical research.

A Formal Analysis of Apple’s iMessage PQ3 Protocol

A detailed overview of the formal verification of Apple's iMessage PQ3 protocol using the Tamarin prover. The talk covers PQ3's hybrid cryptographic design, its post-quantum security goals like forward secrecy and post-compromise security, the powerful adversary model it resists, and the successful formal analysis of its unbounded double ratchet structure.
