Claude traces NIST curve seeds to 1990s timestamps
Claude reveals NIST elliptic-curve seeds originated from 1990s Unix timestamps.
In brief
Claude reveals NIST elliptic-curve seeds originated from 1990s Unix timestamps. Claude traced five NIST elliptic-curve seeds to 1990s C-library random-number generators initialized with Unix timestamps. Originally reported by RuntimeWire.
Anthropic researchers
Anthropic researchers traced five NIST elliptic-curve seeds to 1990s C-library random-number generators.
Published October 16th
The result was published October 16th and addresses a longstanding question about NSA-supplied values.
Not a cryptographic break
Anthropic says the discovery requires no change to how ECDSA is used and is not a cryptographic break.
The takeaway
Claude traced five NIST elliptic-curve seeds to 1990s C-library random-number generators initialized with Unix timestamps.
