Abstract: To provide secure communication over end-to-end data paths or segments of end-to-end paths in a timed deterministic packet network including a plurality of packet engines that perform packet handling, cipher engines are provided separately from the packet engines. The cipher engines are operative to perform at least one cyber security function. A cipher engine and key manager provides central control for the plurality of cipher engines. A centralized packet flow path manager, PFPM, may set up endpoint nodes and intermediate transit nodes of the end-to-end data paths of the packet network.
