Method and apparatus for pattern matching based on packet reassembly |
摘要 |
A method and apparatus for pattern matching using packet reassembly are provided. The pattern matching method using packet reassembly includes: extracting serial information in relation to a current input packet; determining whether or not pattern matching result information in relation to one or more previous packets and/or subsequent packets on the basis of the serial number of the current input packet is already stored; loading the pattern matching result information in relation to the previous packets and/or subsequent packets; and reassembling the loaded pattern matching result information in relation to the previous packets and/or subsequent packets and the current input packet and performing pattern matching with attack patterns which are already stored. Accordingly, by using packet reassembly, a method and apparatus for pattern matching capable of reducing memory usage without lowering the speed can be provided
