    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.

    Abstract: A method and apparatus for updating an encryption key for performing encrypted communication over a communications network. The method comprises, within a timestamp distribution node, transmitting a message to at least one timestamp reception node of the communications network containing a timestamp value. The method further comprises, within the at least one timestamp reception node, receiving the message from the timestamp distribution node and extracting the timestamp value. Wherein, within each of the timestamp distribution node and the at least one timestamp reception node, the method comprises generating at least one updated encryption key for performing encrypted communication based at least partly on the extracted timestamp value.
