| SerializedPayload | string | The serialized payload that is verified by one or more `signatures`. The encoding and semantic meaning of this payload must match what is set in `content_type`. | [optional] [default to null] |
| Signatures | []Grafeasv1beta1Signature | One or more signatures over `serialized_payload`. Verifier implementations should consider this attestation message verified if at least one `signature` verifies `serialized_payload`. See `Signature` in common.proto for more details on signature structure and verification. | [optional] [default to null] |
