Network security is very important for Internet-connected hosts because of the widespread of worms, viruses, DoS attacks, etc. As a result, a network intrusion detection system (NIDS) is typically needed to detect network attacks by packet inspection. For an NIDS system, string matching is the computation-intensive task and hence the performance bottleneck, since every byte of the payload of packets must be checked against numerous predefined signature strings, which may occur arbitrarily indoi:10.1007/978-3-540-74784-0_35 fatcat:2epumeo3ovab5n4hmrnxotl46e
