Anthropic Model Traces NSA Elliptic Curve Seeds to 1990s RNG

Anthropic’s internal research model traced the five elliptic curve seeds the NSA supplied to NIST in the late 1990s to the lrand48 random number generator in an old C library, combined with 1997 and 1998 timestamps, in under half an hour. The model reproduced the widely used P-256 curve sequence, matching the published seed exactly at the 1,842nd candidate. Anthropic said the finding sharply lowers the likelihood of a hidden backdoor and that users of NIST curves need take no action.

The significance here is less about the curves themselves than about what it demonstrates: a research model can reconstruct a decades-old cryptographic provenance question in minutes, turning a long-running suspicion into a testable, reproducible claim. That matters for standards bodies and for anyone relying on legacy elliptic-curve parameters, since the credibility of a seed's origin is now open to automated scrutiny. Anthropic's own conclusion — that a backdoor is less likely — is the takeaway to weigh, but the broader question is whether this kind of provenance tracing becomes routine for other standardized constants.
