A method is performed at a client device distinct from an application server. In the method, a first key is stored in a secure store of the client device. A wrapped second key is received from the application server. The first key is retrieved from the secure store and used to unwrap the second key. Encrypted media content is received from the application server, decrypted using the unwrapped second key, and decoded for playback.
