Sovereign Validation Protocol (SOVP)

SOVP is a protocol for checking, before ingestion, that a signed identity document was produced by the holder of the Ed25519 key published in DNS for a host.

Specification: IETF Internet-Draft draft-litzki-sovp-04 — Individual Submission, Intended Status: Experimental.

Verdicts

The SOVP scanner reports one of three verdicts: CERTIFIED, NOT_CONFORMANT or INCOMPLETE. INCOMPLETE means the host could not be measured, for example because access was blocked during the scan — it is not a statement about the host's quality.

Verdicts are reported in the scan result. They are not part of the signed identity document.

Implementations

  • sovp-python — reference implementation, Apache 2.0 (PyPI: sovp)
  • sovp-agentrust-bridge — maps caller-supplied fields onto an Ed25519-signed AgenTrust TRACE v0.2 record, Apache 2.0
