Attestation Manifest Attestation manifests are attached to the root image index object, under a separate OCI image manifestopen_in_new. Each attestation manifest can contain multiple attestation blobs, with all the of the attestations in a manifest applying to a single platform manifest.

Attestation is a confidential computing keystone. With attestation, workload owners can fully assert the trustworthiness of the hardware and software environment their workload is running in, regardless of the security posture of the underlying infrastructure provider.

Attestation is the act of witnessing the signing of a formal document and then also signing it to verify that it was properly signed by those bound by its contents. Attestation is a legal acknowledgment of the authenticity of a document and a verification that proper processes were followed.

Self-attestation simply requires you to place your signature on a photocopy of the document you want to certify. After you have a made a clean copy of your document, write a statement on it such as: ?True copy? or ?Self-attested copy?. Then place your signature directly under it.

For example, --provenance=false can be used to disable all provenance attestations, while --provenance=true can be used to enable all provenance attestations. By default, a minimal provenance attestation will be created for.

'Signed in my presence by ........ (name of person) ..... and I hereby certify that the contents of this document were read over and explained to the said ..... (name person again) ......... who, to the best of my belief, understood the nature and effect thereof.

You use attestations to authorize specific container images to be deployed on platforms, such as Google Kubernetes Engine (GKE) and Cloud Run. To use attestations, you must require attestations in the appropriate rule of your policy.
