Open publisher page 1 citations

Abstract

String pattern matching is an important algorithm in Intrusion Detection System.Based on the analyzing of KMP and BM algorithms,and of the other improved algorithms,an improved string matching algorithm which is simple,practical and easy to understand is proposed.The experimental results show that the algorithm can reduce the number of times of attempts and comparisons of pattern matching and so improve the efficiency of it.
