摘　　要：入侵检测系统能有效防御网络上多数病毒和非法入侵,但也存在效率问题,特别是在高速网络环境下对检测效率要求非常高。文章提出了一种基于排除算法的模式匹配算法,对入侵检测系统中模式匹配算法[1]进行了改进,使得在实际应用中调用标准模式匹配算法大为减少,提高了系统效率。Although IDS can defend viruses and illegal intrusions effectively on the internet, it has a performance bottleneck when efficiency is highly count, especially on the high - speed network. The article proposed a pattern matc- hing algorithm based on EA algorithm, which improved the pattern matching algorithm of IDS. So it reduced the times of calling the KMP algorithm and improved IDS efficiency.

关 键 词：入侵检测系统 非法入侵 模式匹配 效率
