克勞德在30分鐘內破解25年前的NSA密碼學謎題
anthropic的claude ai在30分鐘內解決了25年前的nsa密碼學謎題，揭示種子來自簡單的c隨機數生成器. 這影響了密碼學安全性和信任。
anthropic's claude ai solved a 25-year-old nsa cryptography mystery in under 30 minutes. the mystery involved seeds for elliptic-curve digital signatures, standardized by nist in 2000. claude found the seeds came from lrand48, a simple c random number generator, initialized with a unix timestamp. this discovery makes deliberate backdoors less likely and impacts cryptography security and trust.
