Abstract
A method for authorizing media content transfer between a home media server and a client device and provisioning DRM credentials on the client device, the method comprising receiving a service authorization credential at a client authorization server from a PKI provisioning server, wherein the service authorization credential is associated with a client device, and sending a validation response from the client authorization server to the PKI provisioning server if the client authorization server determines that the service authorization credential was previously provided by the client authorization server to the client device, wherein the validation response releases the PKI provisioning server to send DRM credentials to the client device.
