Network safe content processing card based on FPGA

Abstract

The invention relates to a network safety content processing card based on FPGA (field programmable gate array). The invention provides a method for solving the problem that contradiction between network safety and network speed and contradiction between network management and network cost are becoming serious. The method comprises giving first place to an FPGA safety chip, adopting a PCI card inserted into a PCI slot of a server, performing data communication with the server by using a PCI express interface protocol, connecting with an outer network through kilomega network ports for completing data receiving and sending, realizing byte-by-byte content detection, content labeling, and flow recombination of the server data under a kilomega line speed, and at the same time, realizing functions of network flow real-time controlling, blocking, inbreak detecting and log auditing. By adopting the invention, networking cost can be reduced, CPU resources of servers can be saved, a CPU can focus on completing other functions, and therefore, the integral performance of the system is improved.

Description

technical field [0001] The invention relates to the technical field of network security content processing, in particular to a server network security content processing PCI board based on a dedicated FPGA security chip. Background technique [0002] With the rapid development of network technology, network security issues have become more and more important. Security incidents such as viruses, worms, hacker attacks, and harmful information on the Internet frequently occur. Virus technology is constantly developing. Viruses use the loopholes in operating systems and applications to spread. At the same time, they integrate technologies such as hackers and Trojan horses. They spread quickly, have strong destructive power, and are highly intelligent. As a result, virus protection cannot rely on a single anti-virus system. Hackers’ attack methods also integrate multiple technologies and use multiple methods. Some network attacks cover a wide range of content. When hackers and ...
