Abstract
Techniques for virtual machine attestation report enhancement via countersigning are described. Upon receiving an attestation report signed by a security processor of a computing device hosting a guest virtual machine in a cloud provider system, the hypervisor can countersign the attestation report to provide further assurance as to the legitimacy of the attestation report and the presence of the computing device within a legitimate data center of the cloud provider.
