Claude AI Solves 25-Year NSA Cryptography Mystery in Under 30 Minutes

Anthropic reported that an internal Claude research model traced the origins of five NIST ECDSA curve seeds in under 30 minutes, resolving a cryptography question that had stood for roughly 25 years without breaking any encryption. The finding addresses the long-unexplained provenance of the seed values used to generate the elliptic-curve parameters in NIST's ECDSA standards.
