Logical Circuits for Extended Content Matching in Hardware Based NIDPS

In this paper we present logical circuits for efficient detection of rolled out contents. As network speed increases and security matters? there is a demand for implementation of hardware based Network Intrusion Detection and Prevention Systems (NIDPS). On the other hand hardware based NIDPS are lacking the flexibility of detection of so named "evasion" techniques. Here we present simple but efficient enhancement to content matching in hardware with minimal basic memory elements (flip-flops) used.
