| Abstract: | This paper presents a pattern matching system that based on FPGA.This paper uses DM9000A to receive network data and uses Snort rule and HashMem function to match pattern.With software simulation the conflict pattern string of Snort rules found out and processed separately.So,conflict can be high-speed solved.The experimental results show that when processing more Snort rules,the system resource consumption increased very little,throughput is not affected,which has more advantage compared to the performance of traditional systems. |
