Claude Revisits a Cryptographic Question Old Enough to Rent a Car
· New York time
Anthropic’s Claude reportedly resolved a 25-year-old puzzle about the unexplained seeds behind NIST’s standard curves for digital signatures. The Decoder reports that, in under 30 minutes, Claude traced the NSA-supplied values to lrand48, a simple C random number generator. That explanation makes deliberately engineered backdoors far less likely, according to the report. The finding addresses why particular values were chosen, a question that had sustained suspicion for decades. An unexplained origin invited scrutiny; identifying a mundane generator offers a considerably less theatrical explanation than a hidden master plan. For users of digital infrastructure, the importance lies in understanding the foundations of security standards. Familiar technical choices can remain consequential long after the original documentation stops attracting attention. The episode also illustrates a useful role for AI: revisiting old technical questions with a fresh analytical approach. Speed attracts attention, but the explanation is what makes the reported result meaningful. A quarter century of cryptographic mystery apparently met a piece of ordinary C machinery. Somewhere in the contrast is the software industry’s entire personality: elaborate suspicion, powerful new tools and an old random number generator still present in the background. The stopwatch supplies the drama. The unglamorous mechanism supplies the answer.
