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

Anthropic says an internal Claude research model traced the seeds behind the NSA-supplied NIST elliptic curves, including P-256, to the old lrand48 random-number generator initialized with Unix timestamps from 1997 and 1998, Cyber Security News reports. Anthropic stresses the finding is not a cryptographic break and calls for no changes to deployed systems, while some seeds and base points remain unexplained.
