SIGNING AND VERIFICATION
Verify release identity before trusting installed code or policy.
Oten Access release trust depends on a platform signing identity, release manifest, artifact integrity, compatibility policy, staged rollout, and a tested response to key compromise or rollback.
System role: Release engineering + Security engineering
Evaluation depends on: Requires release-specific signing identities, checksums, manifests, and verification instructions.
Release verification binds identity, integrity, and version.
Identify
Confirm the expected Oten product, platform, version, distribution channel, and published signing identity for that release.
Verify
Validate the platform signature and notarization where applicable, then compare the artifact checksum and signed release manifest.
Authorize
Confirm the release is allowed by the organization's compatibility and rollout policy before installation or activation.
Attest
Record the installed version, signer, manifest identity, policy generation, and verification result as operational evidence.
The updater is a separate trust boundary.
- Authenticate update metadata and payloads independently.
- Reject unauthorized downgrade and incompatible component combinations.
- Stage rollout with health evidence, explicit activation, and bounded rollback.
- Preserve last-known-good enforcement only within its signed validity and compatibility boundary.
- Treat bootstrap, fixed-path platform integrations, and normal component releases according to their distinct rollback contracts.
Signing-key compromise requires a recovery plan before release.
- Revoke the affected identity and determine the exact artifact and release exposure window.
- Publish customer guidance with affected versions, trusted replacement identity, and verification steps.
- Rotate trust bundles through a path that does not rely only on the compromised key.
- Re-verify installed components, policy state, update metadata, and rollback images.
- Preserve incident and remediation evidence for affected customers and assurance review.
