摘要
Abstract
Intrusion detection system ( IDS), as a rational supplement to the firewall, has been developed to be one of the key components of the network security system.IDS is facing new challenges due to fast development of network technology and therefore needs to be improved of its system performances through all kinds of approaches, and the operation efficiency of rule matching module, the hard core of IDS, is straight effected by the performance of pattern matching algorithm.Through thorough analysis on primary Boyer-Moore algorithm, the BM algorithm is ameliorated and implemented in this paper based on the thought of increasing glide distance while the pattern does not match.Experiment proves that this method improves the efficiency of pattern matching.关键词
