Claude solves decades-old mystery behind NSA cryptographic numbers (cyberinsider.com)

Anthropic's Claude AI has unveiled the origins of cryptographic numbers that have puzzled experts for decades, revealing they stem from a conventional random-number generator initialized with timestamps from the late 1990s. This breakthrough addresses concerns regarding whether the NSA intentionally chose these numbers to embed hidden vulnerabilities in security standards. By reconstructing the seed parameters for five mathematical curves utilized in the Elliptic Curve Digital Signature Algorithm (ECDSA), Claude identified recognizable patterns and confirmed that the initial state was derived from the lrand48 generator, specifically using Unix timestamps. This significant discovery bolsters the integrity of widely adopted cryptographic standards published by the U.S. National Institute of Standards and Technology (NIST) in 2000, ensuring that the parameters, while public, pose no risk to users' private keys or encrypted communications. It alleviates long-standing fears of potential backdoors, thereby enhancing trust in digital security frameworks. Despite some unresolved questions about certain seeds and skipped candidate curves, Anthropic's findings considerably clarify the history of these cryptographic standards, reaffirming their robustness in contemporary applications. The research was independently verified by cryptographer Filippo Valsorda, who confirmed the results and awarded a charitable payout to a relevant organization.
