| 摘 要： | 基于特征匹配技术的入侵检测系统的速率和效率常常依赖于模式匹配算法的精确性,而算法的效率又依赖于算法的选择和实现方式。随着网络技术的发展,匹配算法优劣有可能成为入侵检测系统的瓶颈,因此要提高入侵检测系统的性能必须对原有算法改进或提出新的算法,本文在对经典BM算法分析、研究的基础上,对该算法进行了部分改进,并给出了基于该改进的新的匹配算法。

| Abstract: | The speed and efficiency of feature-based matching technique for intrusion detection systems are often dependent on the accuracy of pattern matching algorithm.Meanwhile,the efficiency of the algorithm also depends on the choice of algorithms and ways of implementation.With the development of network technology,pros and cons of matching algorithm may become a bottleneck of intrusion detection systems.Therefore,in order to improve the performance of intrusion detection systems,we must improve the original alg... |
