The rapid development of Internet brings us much convenience,while such illegal activities on Internet as network intrusion hampers the normal use of the Internet.Highly-efficient rule processing systems could prevent the network from being attacked.For the processing speed of current rule matching algorithms is slow,and could not keep up with the high-speed back-bone network security applications,a new rule matching algorithm based on hardware is proposed,which implements rule matching by vector operation.The vector operation is realized in parallel processing on hardware,thus accelerating the rule matching speed greatly.A hardware model of rule matching is designed and implemented.Simulation experiment indicates that the performance of this algorithms could satisfy the requirement of IDS data processing in the high-speed back-bone network.
