Claude Reconstructs Seed Generation Process for NIST Elliptic Curves
Anthropic's AI model Claude has reconstructed how the original seed values for several widely used NIST elliptic curves were generated. The research resolved a question surrounding the provenance of parameters provided by the U.S. National Security Agency over two decades ago. Claude identified that the process involved a C library pseudorandom number generator and Unix timestamps. For the P-256 curve, the model required 1,842 iterations through candidate outputs to reproduce the standardized seed. Anthropic emphasized that the discovery does not reveal any attack or security vulnerability on the affected curves.
