Anthropic 研究称 Claude 查明了 ECDSA 曲线参数的选取方式。ECDSA 是使用椭圆曲线创建和验证数字签名的算法，其更知名的前身是 DSA。1990 年代末，NSA 提供了这些曲线背后的种子，但未解释来源；研究发现它们只是一个基础随机数生成器的输出，并以时间戳作为种子。相关研究见 https://www.anthropic.com/research/ecdsa-curve-origins。

Claude figured out how the curve parameters for ECDSA were chosen
ECDSA is an algorithm for creating and verifying digital signatures using elliptic curves. You might know its older more well known sibling DSA.
In the late 1990s, the NSA supplied the seeds behind these curves used for ECDSA with no explanation of where they came from
turns out they're just output from a basic random number generator, seeded with a timestamp
