Install Image Attestation For Free

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.

What are Confidential Containers? Confidential Containers (CoCo) is a new sandbox project of the Cloud Native Computing Foundation (CNCF) that enables cloud-native confidential computing by taking advantage of a variety of hardware platforms and technologies.

Attestation Date: Defines the date on which the attestation task was initiated, and the point in time with respect to the attestation data that the user must attest to. Note that the reviewer does not attest to what the user has today. They attest to what the user had on the date specified in the attestation task.

The attestation process uses a series of measurements that are unique to an enclave. You can use these measurements to create access policies in external services to grant the enclave access to special cryptographic operations.

A single attestation can authorize identical images that are stored in multiple different locations or different registries, such as Artifact Registry, Container Registry, or an external container registry. At deploy time, Binary Authorization uses attestors to verify attestations.

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.

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.
