    Claude discovered the origin of the seeds of the NIST elliptic curves of the ECDSA standard.

    • The seeds of P-192, P-224, P-256, P-384 and P-521 come from no hashing algorithm.

    • The lrand48 generator of the C library, initialized with a Unix timestamp, produced these seeds.

    • According to Anthropic, the discovery makes the presence of deliberate backdoors in the curves much less plausible.

    • The binary seed B-163 remains unexplained, as do the base points of P-224, P-256, P-384 and P-521.
