Claude reveals ECDSA curve origins
Anthropic says its research model traced the seeds behind long-used elliptic-curve constants to a timestamp-based random process.
TL;DR
- Anthropic says its research model Claude traced the origins of constants used in the ECDSA elliptic-curve signature standard.
- The company says the model identified a timestamp-based random-generation process as a possible source of the historical seed values.
- The account is based on Anthropic’s research description; it does not establish that ECDSA is broken or that existing signatures are invalid.
Anthropic said its research model Claude traced how certain constants used in the ECDSA elliptic-curve digital-signature standard were generated. The company described the work as an investigation into the unexplained origin of seed values used in the standard. [1] [2]
Anthropic said researchers asked the model to identify the seed-generation method without supplying the answer, and that it arrived at a process involving timestamps and a simple random-number generator. Investing.com also reported the company’s account of the discovery. [1] [2]
The detailed method and evidence available for review currently come from Anthropic’s description. The claim concerns the historical origin of constants; it is not a report that ECDSA has been shown to be vulnerable or that existing signatures have become invalid. [1] [2]
Independent reproduction and assessment by cryptographers would help establish how strongly the evidence supports the explanation. Anthropic has described its research process, but the breadth of external validation remains unclear. [1] [2]
Why it matters
The report is an example of a model being used to investigate cryptographic history. Its significance depends on independent reproduction, and the company’s account does not itself imply a weakness in ECDSA.
Editor's note
Attributes the discovery claim to Anthropic and does not characterize it as a demonstrated cryptographic vulnerability.
