摘要： An example communications apparatus includes a plurality of communicatively-interconnected communications domains and an electronic switch, integrated as part of a first domain of the plurality of communicatively-interconnected communications domains. The electronic switch effects secure communications of data over the one or more channels specific to the first domain, by using a first circuit and a second circuit. The first circuit is used to obtain and process sampled channel properties associated with the one or more channels specific to the first domain. The second circuit is used to generate, in response to the first circuit, a domain-specific code that is generated pseudo-randomly using the processed sampled channel properties, the domain-specific code being used for coding data conveyed over the one or more channels specific to the first domain.

摘要： 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.

摘要： An example network communication device includes 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.

摘要： A time manager controls one or more timing functions on a circuit. The time manager includes a data storage and a time calculator. The data storage device stores a first indication of a performance characteristic of a memory cell at a first time. The data storage device also stores a second indication of the performance characteristic of the memory cell at a second time. The time calculator is coupled to the data storage device. The time calculator calculates a time duration between the first time and the second time based on a change in the performance characteristic of the memory cell from the first indication to the second indication.
