Abstract
A processing system to serve as a source device for protected digital content comprises a processor and control logic. The processing system may generate and save a first master key, and may transmit that key to a first receiving device for use during a first session. During a second session, the processing system may obtain an identifier for a candidate receiving device. The processing system may use the identifier to determine whether the processing system contains a master key for the candidate receiving device. If the processing system such a master key, the processing system may send verification data concerning that key to the candidate receiving device, and may use that key to encrypt a session key for the second session. If not, a second master key may be generated and transmitted to the candidate receiving device for use during the second session. Other embodiments are described and claimed.
