Analyzing Group Chat Encryption in Messaging Applications

This talk details a formal security analysis of group chat encryption algorithms in popular messaging applications like MLS, Session, and Keybase. It introduces Symmetric Sign Encryption (SSE) to model these protocols, identifying critical vulnerabilities such as insider replay and reordering attacks in MLS and Session due to insufficient context binding. The analysis highlights the complexities of key-dependent messages and key reuse, demonstrating how formal methods can pinpoint subtle design flaws and suggest robust mitigations for real-world secure communication.

🔬 The Physical World Is More Forgiving Than You Think — Anima Anandkumar, Caltech

Anima Anandkumar discusses her vision for AI in science, moving beyond language models to apply machine learning to the physical world. She introduces neural operators, especially Fourier neural operators, as a solution to data scarcity and resolution challenges in domains like weather, climate, and fusion. These models integrate physical constraints and data to achieve unprecedented speed and accuracy, even on consumer hardware, enabling capabilities from early hurricane prediction to digital twins for fusion reactors and inverse design for advanced materials. The conversation highlights the need for principled AI design for scientific discovery and advocates for distinct regulatory approaches for AI in science.

Session on Reasoning

This session features two talks on optimizing and verifying AI reasoning. Hongxiang Fan discusses cross-stack co-design for efficient AI, focusing on Test-Time Scaling (TTS) challenges, optimal verification granularity, and system-level optimizations for edge deployments. Nagarajan Natarajan introduces 'Advancing Verified Reasoning' with the InterVent platform, aiming to ensure AI agents comply with complex policies through formal verification, dynamic steering, and leveraging verification signals for training. Both emphasize addressing the computational and reliability costs of advanced AI.

Terence Tao – Kepler, Newton, and the true nature of mathematical discovery

Terence Tao uses the story of Kepler's discovery of planetary motion as an analogy for AI's role in science. He argues that AI excels at broad, high-temperature idea generation but requires a robust verification process to be useful. The bottleneck in science is shifting from hypothesis generation to verification and curation, a challenge current scientific structures are not equipped to handle. Tao foresees a future of human-AI collaboration where humans provide deep insights and AI explores the vast breadth of possibilities, ultimately making scientific papers richer but not necessarily deeper.

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.
