Sixty Hours of AI Cryptanalysis Retired the Hawk Signature Scheme
An Anthropic frontier model found a hidden lattice symmetry that roughly halves the lattice dimension needed to attack Hawk, and the team withdrew the scheme from NIST's process a day later. AI-assisted cryptanalysis is now a working method, with direct consequences for post-quantum cryptography buyers and the case for crypto-agility.
Entanglement Survives 62 Kilometers of Ordinary Aerial Fiber
A NIST, Joint Quantum Institute and Qunnect team sustained entanglement distribution across a 24-hour trial, at 92.8 percent uptime, over 62 kilometers of noisy aerial telecom fiber, moving quantum key distribution links from bespoke builds toward existing infrastructure.
