The Reconfigurable Host-Based IPS Processor is developed for a highly accurate detection of unauthorized computer access in a smartphone or a personal computer with battery operation. The processor is composed of MAC Unit, Firewall Logic Unit with LUTs for Intrusion Prevention and a CPU. Each unit is connected with a bus to carry Ethernet frames. That is, a huge number of wiring is required. In this study, a multiplexed bus is developed by using wave-pipeline technique aiming at a highly effective packet forwarding. The bus is evaluated, and the multiplexing operation of the bus is confirmed. In addition, the performance of the CPU needed in the processor is evaluated and cipher strength of the wireless LAN in the processor is strengthened.
