발전소 제어네트워크 보호용 FPGA기반 침입탐지 알고리즘 구현

초록

In this paper, we proposed a system based on FPGA to inspect packets in real time in a closed control network environment such as a power plant network. The proposed system is a whitelist-based packet-carrying system that allows only communication between authorized network nodes registered in advance, and is designed to monitor communication between up to 256 nodes in real time. The proposed structure was implemented with verilog by utilizing Xilinx FPGA xc7a100tftg256-1.
