Abstract

The invention provides a data packet verification method and a data packet verification system. The data packet verification method comprises the steps of receiving a to-be-verified data packet by a server; receiving the to-be-verified data packet and a regular expression for verifying the to-be-verified data packet from the server by the FPGA; parallelly calling a plurality of micro-kernels for executing the regular expression by the FPGA and verifying the to-be-verified data packet; combining verification results of the micro-kernels by the FPGA and transmitting a combined verification result to the server. A parallel regular expression algorithm which is realized based on the FPGA realizes algorithm acceleration in a shorter period and supports high-speed real-time data packet checking. The FPGA can simultaneously and parallelly call a plurality of algorithm operation kernels according to the requirement, thereby realizing algorithm improvement by times.

Description

technical field

[0001] The invention relates to the field of information security, in particular to a data packet verification method and system. Background technique

[0002] In order to ensure the security of information, the existing technology provides a variety of verification methods. Among them, regular expressions have become a software tool language for network data detection and identification because of its special data processing characteristics.

[0003] On the server, the software-based regular expressions execute instructions in a serial manner. Today, with the development and popularization of the Internet, it is becoming more and more difficult for the server to check massive network data packets, and it is difficult to further improve the detection speed. Contents of the invention

[0004] The invention provides a data packet verification method and system to provide a new data packet verification method.

[0005] The invention provides a data packet ver...
