Anthropic’s AI model Claude has unraveled a 25-year-old mystery in cryptography by discovering the origin of the seed values used in the US National Institute of Standards and Technology’s (NIST) elliptic curve digital signature algorithm (ECDSA) curves. For decades, security researchers and cryptographers harbored suspicions that US government agencies might have embedded backdoors into widely used cryptographic standards. Claude’s analysis successfully traced the exact mathematical constants and origins of the seeds, confirming they were generated systematically rather than maliciously. The breakthrough demonstrates the expanding analytical power of advanced AI models in complex mathematical and cryptographic domains.
