入侵检测系统的融合模式匹配算法

Intrusion Detection System Integration Pattern Matching Algorithm

运用入侵检测系统的融合模式匹配算法取得待匹配的字符串集合的公共前缀与文本匹配,若为单模式匹配则匹配结束,若为多模式匹配则将文本被分割成的字符串集中的字符串分别与模式串匹配,该融合算法对单模式匹配和多模式匹配均提高了效率,识别了正文的大小写。

To use the integration of intrusion detection system pattern-matching algorithm obtain the public prefix of the string which is to be matched string. The public prefix match the text. If it is a single pattern-matching, the matching end; if it is a multi-pattern matching, the text split into multiple strings, each string is to matched with the pattern string, using the fusion algorithm, pattern matching pairs of single-and multi-pattern matching are more efficient, and can distinguish between uppercase and lowercase letters of text.
