Abstract
Technology is described for allowing playback of protected media content on an untrusted device. A request to entitle playback of the protected media content may be received from a trusted device. The request may include an outer encrypted message with location information for the trusted device and identity information for the trusted device and a nested encrypted message with a signed challenge processed by the untrusted device. An entitlement for the playback of the protected media content may be generated in response to verification of the request in the outer encrypted message and the nested encrypted message. The entitlement may be sent to the untrusted device via the trusted device. The entitlement may enable the untrusted device to play the protected media content for a defined duration.
