US Patent 10461937 Hypervisor supported secrets compartment

A secret is securely maintained on a virtualized computer system by configuring a specialized virtual machine to manage and maintain the secret on behalf of an application. When the application requests access to the secret, a controlling domain, in combination with the specialized virtual machine, validates that the application is authorized to make the request and that the application has not been compromised prior to making the request. If the request is validated, the controlling domain and the specialized virtual machine fulfill the request by providing the application with access to the secret.
