Abstract
An example network communication device include a communication circuit and a processing circuit. The communication circuit securely communicates over a network using a rotating code and the processing circuit enter a sleep mode at which time values of the rotating code are unknown by the network communication device. The processing circuit enters the sleep mode by requesting another network communication device of the network to authorize entering the sleep mode, and entering the sleep mode responsive to an indication verifying that the network communication device and the other network communication device agree on a set of secure parameters that is created pseudo-randomly, wherein the processing circuit enters the sleep mode with the set of secure parameters as stored for awakening but without storage of the values of the rotating key.
