Abstract


With the rapid development of network technology , more and more information is transmitted over the Internet , information sharing has become the development trend of today 's networked society , people enjoy the network of information sharing , but also had to face some Internet and breeding the distress caused by viruses, network attacks and other illegal means , the firewall have come into being . Improve network bandwidth , the diversification of network applications and attacks to the firewall serious challenges to the traditional single packet filtering the the state detection software firewall has far short of needs , become performance bottlenecks and functional single the challenge of network security . This paper first introduces the current security filtering system , analysis of the pros and cons of the various security filter architecture , high performance and flexibility embodied in the network processing on FPGA (Field-Programmable Gate Array) , a Based on NetFPGA dynamic configuration online filtration system. Followed by brief framework of the overall design of the system , and then details the methods and processes of each module of the system implementation , concluded the entire design process and propose areas for improvement . In this paper, FPGA implementation of packet filtering and stateful inspection firewall , the traditional detection state table space , a new storage status table method , the amount of space occupied by far less than the traditional state detection ; realized by FPGA part of the snort rules , the reference computer RISC (Reduced Instruction Set Computer) instruction set thinking, snort rules classify statistics extracted centralized rules field rules , design content detection template , and then use the hardware implementation of other rules software implementation . Packet filtering to provide on the the header static filtering , state , and content inspection to provide the payload motion detection , to detect and report the phenomenon of abnormal or unauthorized network system , a move a quiet , complement each other . The same time , both parallel matching string matching method , 30 parallel matching rules , content inspection acceleration matching ; with RAW Socket programming , remote configuration stored in NetFPGA filtering rules . This paper systematically from the hardware and software implementation , algorithm design to complete research on dynamically configurable online filtering technology .
