Hashing + Memory = Low Cost, Exact Pattern Matching
by Giorgos Papadopoulos, Hardware Laboratory — 2005 — in Proceedings of 15th International Conference on Field Programmable Logic and Applications
…In this paper we propose the combination of hashing and use of memory to achieve low cost, exact matching of SNORT-like intrusion signatures. The basic idea is to use hashing to generate a distinct address for each candidate pattern, which is stored in memory. Our implementation, Hash-Mem, uses simp…

On the importance of header classification in hw/sw network intrusion detection systems
by Vassilis Dimopoulos, Giorgos Papadopoulos, Dionisios Pnevmatikatos — In Proceedings of the 10th Panhellenic Conference on Informatics (PCI
…Abstract. In this paper we examine the impact of various levels of (partial) hardware acceleration levels on a software based Network Intrusion Detection System. While complete hardware solutions are possible and have been studied extensively, they are costly and may suffer from scalability and flex…
