The invention particularly relates to a multi-chip network encryption system based on physical isolation. The multi-chip network encryption system based on physical isolation comprises a management control card, an intranet communication card, an extranet communication card and a network password card, wherein the intranet communication card, the extranet communication card and the network password card are all connected to the management control card; and the intranet communication card and the extranet communication card are respectively connected to an intranet and an extranet. According to the multi-chip network encryption system based on physical isolation, the intranet and the extranet are physically isolated; through a Rapid IO high-speed interface, high-speed transmission of network data is guaranteed, meanwhile, the speed for matching network data encryption and decryption and a strategy is improved by adopting a hardware encryption and decryption method, so that the whole system can run under the speed of a gigabit network, and high-speed data encryption and decryption and remote centralized management are implemented.
Description
technical field [0001] The invention relates to the technical field of network encryption data transmission, in particular to a multi-chip network encryption system based on physical isolation. Background technique [0002] With the continuous development of information technology, network interconnection has become an irresistible trend. However, this interconnection method is extremely vulnerable to various attacks, resulting in illegal access to the internal network and information leakage. Criminals attack the hardware and software of the network system and the data in the system by taking advantage of the loopholes and security defects in the network. Especially in recent years, there have been new development trends in network attack technologies and attack tools, which have brought unprecedented risks to organizations that rely on the Internet to run their business. [0003] In order to solve the problem of Internet network security and ensure the safe and stable op...
