Abstract

This paper introduces a novel FPGA-based signature match co-processor that can serve as the core of a hardware-based network intrusion detection system (NIDS). The co-processor is based on simple shift registers and bitmap encoders for the efficient signature match in hardware. As compared with related work, experimental results show that the proposed work achieves higher throughput and less hardware resource in the FPGA implementations of NIDS systems.
