摘要
Network Intrusion Detection Systems (NIDS) have become widely recognized as powerful tools for identifying, deterring and deflecting malicious attacks over the network. New generations of network intrusion detection systems create the need for advanced pattern-matching engines. This paper proposes an improved AC algorithm, called Semi-AC. We contribute modifications to the Aho-Corasick string-matching algorithm that drastically reduce the amount of memory required. Its efficiency is close to the standard AC, but the space is saved 50% or more.
