    摘要: A method is disclosed that receives, at a sink device, encrypted content. Further, the method receives, at the sink device, content license data from a source device. In addition, the method analyzes the content license data to determine whether a rights issuer that generated the content license data intended that the source device, which has cryptographic access to the content license data, be authorized to send, to the sink device, a value that enables decryption of the encrypted content. The method also receives the value and decrypts the encrypted content if the rights issuer intended that the source device be authorized to transfer the value to the sink device.
