JP Aumasson on Quantum Risk, AI Attacks and Too Much Crypto

Episode Description from the Publisher

This week, Anna, Tarun and Nico are joined by JP Aumasson, co-designer of BLAKE3, author of Serious Cryptography and cryptography engineer at Cloudflare. They revisit the quantum threat to cryptography, looking at recent advances in quantum attacks on RSA and elliptic-curve cryptography, and discuss why JP remains cautious about predictions of an imminent “Q-day.” They then explore how AI is changing cryptanalysis, from recent RSA factoring records to the growing divide between symmetric and asymmetric cryptography. The conversation then turns to Poseidon and recent attacks that have challenged confidence in ZK-friendly hash functions, as well as China’s new NGCC competition, where AI is already being used to find weaknesses in candidate designs. JP shares his experiments using AI for cryptanalysis, why it could accelerate both the building and breaking of cryptographic systems, and a introduces a project exploring AI-driven attacks on hash functions.   Related Links   Too Much Crypto by Jean-Philippe AumassonSecuring Elliptic Curve Cryptocurrencies against Quantum Vulnerabilities: Resource Estimates and Mitigations Flock: Fast Proving for Batch Boolean ComputationsFlock ChallengePOSEIDON: A New Hash Function for Zero-Knowledge Proof Systems (Updated Version) Ngcc.devChinese NGCC Algorithms: The First Week of AI CryptanalysisJP Aumasson PapersYukon.orgZK Podcast Episode: The Quantum Question Panel – Live from zkSummit14!ZK Podcast Episode: Quantum Advances, Hybrid Signatures and SNARKs to the Rescue with Dan Boneh     Sovright builds the critical infrastructure that preserves your right to choose.
