Sixty Hours of AI Cryptanalysis Retired the Hawk Signature Scheme
An Anthropic frontier model found a hidden lattice symmetry that halves Hawk's security level, 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 held entanglement distribution open for 24 hours over 62 kilometers of noisy aerial telecom fiber, moving quantum key distribution links from bespoke builds toward existing infrastructure.
