  • 摘要:In intrusion detection among different hardware approaches, memory-based architecture has attracted a lot of attention be-cause of its easy reconfigurability and scalability. In order to accommodate the increasing number of attack patterns and meet the throughput requirement of networks, a successful network intrusion detection system must have a memory-efficient patternmatching algorithm and hardware design. In an efficient pattern matching algorithm for memory architecture, state traversal algorithm was used to significantly reduce the memory requirement. In this paper, an adaptively dividable dual-port TCAM is proposed to further reduction of the memory requirement by which we can achieve a highthroughput, low-power, and low cost pattern detection processor for mobile devices. The proposed dual-port TCAM is realized with the dualport AND-type match-line scheme which is composed of dual-port dynamic AND gates. The dual-port designs reduce power consumption and increase storage efficiency due to shared storage spaces. The method readily generalizes to higherdimensional pattern matching problems
