Claude Traces NIST Cryptography Seeds To An Old Random-Number Generator

An unusual piece of cryptography history has gained an answer. Anthropic says Claude reconstructed how the original seed values behind several widely used NIST elliptic curves were generated, resolving a question that had attracted suspicion for more than two decades. TL;DR: Claude identified a process involving the C library’s lrand48 generator and Unix timestamps. Anthropic stresses that the research does not reveal an attack on P-256 or other affected curves. The seeds have mattered because the standards published their values without a convincing public account of how the numbers were chosen. The U.S.
