Cross-domain secure communication transmission system and method based on dark network path finding

Abstract

The invention provides a cross-domain secure communication transmission system and method based on dark network path finding. The cross-domain secure communication transmission system comprises a plurality of gateway devices and a plurality of public network servers in communication connection with the plurality of gateway devices. The plurality of gateway devices are used for processing content semantic conversion and data encryption of the cross-domain service data and selecting a hidden transmission path, and the plurality of gateway devices are deployed at network boundary outlets of different information service domains. The plurality of public network servers are used for undertaking the transmission transfer service of the cross-domain service based on dark network path finding in apublic network, and the plurality of public network servers are deployed in the existing cross-domain public network. According to the invention, a cross-domain data communication target can be effectively hidden, data behaviors can be hidden, man-in-the-middle analysis can be avoided, communication nodes can be planned, and service between different information domains is achieved; and in the transmission process in the public network, transmission nodes are hidden, data semantics is converted, and a security algorithm for communication between the nodes is adopted, and therefore secure transmission of cross-domain data in an existing network environment is guaranteed.

Description

technical field [0001] The invention belongs to the field of communication technology, and in particular relates to a dark network-based cross-domain secure communication transmission system and method. Background technique [0002] Against the background of big data, 5G, and military-civilian integration industries, the degree of informatization in the economy and society is getting higher and higher, and business integration is bound to bring about the rapid development of the information industry. Business information that was originally independent of each other can provide people with more convenient, intelligent, and humanized services through information fusion, thereby meeting the growing diversified needs. Corresponding information fusion is bound to introduce communication security risks brought by data fusion communication. [0003] Existing network communication security is mainly guaranteed through three aspects, which are environmental security, data security,...

AI Technical Summary

Problems solved by technology

Under the environment of existing infrastructure, environmental security can already be guaranteed. Therefore, how to ensure communication security on this basis needs to consider how to strengthen data security and behavior security under the existing communication security system. Existing network data The field of communication security is concentrated in several categories: firewalls, gatekeepers, bastion machines, gateways, etc., but these mainstream communication security devices have problems such as open technical principles, intermediary interception, traceable sources, and statistical data.

As the interests of the information economy in the digital industry are increasing, it will inevitably bring greater temptation to some unscrupulous practitioners, which will bring greater challenges to network information transmission
