Claude AI Uncovers Source of NIST ECDSA Curve Seeds
Researchers at Anthropic utilized the AI model Claude to solve the long-standing puzzle of the initial values for NIST and ANSI elliptic curve cryptography standards. Claude's investigation into 1990s C programming libraries revealed that these seeds were produced by the lrand48 pseudorandom number generator, seeded with Unix time values. This discovery bolsters the belief that the curves were selected without hidden weaknesses.
