【 摘 要 】

Problem statement: In this study we discus about Signature Detection Technique (SDT)used in Network Intrusion Detection System (NIDS). Design of SDT using Content AddressableMemory (CAM) is discussed. Approach: Two novel architectures, XOR and ones count based Precomputation CAM architectures are proposed and implemented in third party back end tool with 0.18mm technology, power consumptions are compared. Results: Proposed architecture consumes 90%less power added with 5.2% increment in speed. Conclusion: Power reduction was achieved byreducing the number of bit comparisons of pre computation technique.
