Claude reveals ECDSA curve origins

Readers should take this as a fun closing chapter and the end of years of speculation. There is no action to be taken or things to do differently. Most researchers trusted the curves already. Enjoy. ECDSA is the most widely used elliptic curve cryptography standard. It was adopted by NIST in 2000 as part of the FIPS 186-2 Digital Signature Standard which lists a set of standard elliptic curves of

Anthropicの社内研究モデルが30分未満で、P-256などNIST楕円曲線のシードの由来を特定。Unix時刻で初期化したlrand48の出力として再現。長年のバックドア疑念を弱める成果と説明し、再現コードも公開。

NSAのバックドア疑惑を抱えてた楕円曲線がただのタイムスタンプだったオチ面白すぎるだろ
