Signed Log
A data structure that computes a hash chain over structured events in chronological order and applies digital signatures, providing integrity, non-repudiation and verifiability.
Timeline (last 90 days)
In the signed record, the approval event precedes the tool request event, thereby proving that the tool ran only after human approval.
A signed record is a data structure that computes a hash chain over a set of structured events in chronological order and digitally signs the final digest with an asymmetric key.
A signed record has three core properties: integrity (any tampering with an event breaks the hash chain), non-repudiation (the signer cannot deny having generated the record), and verifiability (a third party can verify the signature and the event order using only the public key).
