The NIST Elliptic Curves Seeds Bounty Has Been Claimed
We now know how the seeds of the NIST elliptic curves were generated: they’re not the hash of some saucy sentence, but the output of drand48() seeded with the time, which was indeed in 1997-98.
Quick read
A blog post revealing that the NIST elliptic-curve seeds were generated by the POSIX drand48() RNG seeded with the 1997-98 UNIX time, and that an Anthropic team claimed a bounty for solving the riddle. Readers interested in cryptographic history and curve trustworthiness would visit to learn how the seeds were produced and what it implies for NIST curve security.
- Anthropic reproduced seeds using srand48()/drand48() and timestamps
- Findings rule out certain backdoor-conspiracy attacks on NIST curves
- Author donated the bounty to ISRG, raising 36 Ki$
