Claude 不到 30 分钟破解 NSA 25 年椭圆曲线种子之谜
原标题：Anthropics' Claude cracks a 25-year-old NSA cryptography mystery in under 30 minutes
AI 摘要
Anthropic 的 Claude 在不到 30 分钟内破解了一个困扰业界 25 年的 NSA 椭圆曲线种子来源之谜。NIST 于 2000 年标准化的 ECDSA 曲线参数由 NSA 提供种子值，但从未解释其生成方式，引发后门疑虑。Claude 发现这些种子来自以 1997 年 5 月至 1998 年 4 月间 Unix 时间戳初始化的 C 语言随机数生成器 lrand48，因其仅输出 31 位导致部分种子高位系统性为零。Anthropic 认为这降低了蓄意后门的可能性，并将 36,864 美元赏金捐给互联网安全研究小组。

Anthropics' Claude cracks a 25-year-old NSA cryptography mystery in under 30 minutes Anthropic's AI Claude has solved a 25-year-old cryptography mystery. NIST standardized several curves in the ECDSA standard, the most widely used framework for elliptic-curve digital signatures, back in 2000. The NSA had supplied the seeds, the starting values used to generate the curve parameters, with zero explanation. No one knew how they were created, and that fueled suspicion of possible backdoors. The myst
