Abstract
Pattern matching algorithm is a key technology of intrusion defense system in computer network. Based on the pattern matching algorithm AC-BM, This paper proposes an structure of binary tree to express the pattern tree , the structure model of binary tree can reduce the time of forming pattern tree, and then through the using of improved BMHS algorithm of bad character, the algorithm can increase moving distance of pattern tree decrease the matching time, and promote the speed of pattern matching. The experimental data show that, through the improvement of AC-BM algorithm, it indeed can improve the matching speed, achieving good time performance.
