摘要
基于免疫原理的入侵检测系统中,很重要的一环就是字符串的匹配,现在的研究中主要采用的匹配规则是r连续位匹配。在r连续位匹配算法中,r值的大小决定着系统的时间开销和检测效率。因此,研究r连续位匹配算法中r值的选择十分必要,选择正确的r值可以在保持较少时间开销的情况下保证检测器的质量。
String matching is a very important part in Intrusion Detection System based on Immunity, r-continuous bits matching rule is the major rule in present study. In the r-continuous bits matching rule, the time consuming of the algorithm and detection efficiency determined by the value of r. Therefore, choice a right r value can guarantee the quality of the detector in the case of to maintain less time overhead.
