摘　　要：随着国家信息化的不断推进和计算机网络飞速发展,网络信息审计成为不可或缺的一部分。网络信息审计系统从网络关键点采集数据包,对其传送内容进行审计分析,达到网络信息内容的监控。在网络信息审计系统中,需要对大量的关键特征串进行按序匹配,目前的ACSM算法只是实现了单字符的跳转状态机,仅能够匹配出单个的字符串,却未实现特征串的按序跳转,不能满足网络审计系统识别网络应用的需求。经过对ACSM算法的改造,创建了特征字符串的动态跳转状态机,满足了网络信息审计系统对特征字符串按序匹配从而识别出网络应用的需求。with the continuous progress oil.national informatization？and the rapid development？of computer？network, the network information audit has become an indispensable part of network information audit system. The network information audit system collects data package from the key point of network, performs audit and analysis for tnmsfer content and monitors network information content. In the network information audit system, it is necessary, to perform matching in sequence for varions key feature strings. The existing ACSM algorithm only realizes the jump state machine which can only match single character strings, not realize jumping in order of feature string, and thus not meet the reqnirements of network application identification of network audit system. Tbe dynamic jump state machine of feature character string is created by improving ACSM algorithm to meet the requirement of feature character string matching in order and network application identification of network information audit system.
