Network security isolation and information exchange method and system based on one-way channel

Abstract

The invention provides a network security isolation and information exchange method and system based on a one-way channel and belongs to the field of computer network security. The network security isolation and information exchange system comprises a data acquisition module, a protocol reassembling module, a data audition module, an information unloading and packaging module and a data transmission module. Each module can be acquired through hardware or/and software. The network security isolation and information exchange method includes the steps of data acquisition, protocol reassembling, data audition, information unloading and packaging, data transmission and the like. The one-way channel is adopted for transmitting data, the transmitted data are audited and unloaded through a special data package processing method, and when a fault occurs, physical isolation is formed. According to the network security isolation and information exchange method and system, the data throughput rate can be remarkably increased, data security between different networks can be effectively protected, illegal user intrusion and control are avoided, and system cost is reduced.

Description

technical field [0001] The present invention relates to the field of computer network security, more precisely, the present invention relates to a network security isolation and information exchange method and system thereof. Background technique [0002] Informatization is the mainstream trend of world science and technology and social development. The national economy and society are increasingly dependent on information and information systems. The application of information and communication technology has penetrated into all aspects of people's production and life. Communication equipment between networks has become It has become a basic tool for communication between different institutions and individuals. While enjoying the convenience brought by the Internet, we are also plagued by problems such as malicious code attacks, hacking, and information leakage. On the one hand, the information exchange between different networks must meet the requirements of information s...
