Efficient and safe image data network one-way physical channel importing system and application thereof

Abstract

The invention discloses an efficient and safe image data network one-way physical channel importing system and the application of the efficient and safe image data network one-way physical channel importing system. The efficient and safe image data network one-way physical channel importing system comprises an outer network device, a one-way dedicated exchange passageway and an inner network device. The outer network device comprises an outer network server and a sending sub-system. The one-way dedicated exchange passageway comprises a sent-data exchange card, a one-way signal transmission module and a received-data exchange card. The inner network device comprises a receiving sub-system and an inner network server. By the adoption of the efficient and safe image data network one-way physical channel importing system and the application of the efficient and safe image data network one-way physical channel importing system, it can be guaranteed that a physical channel is absolutely unidirectional, and the importing system is suitable for deployment between networks at different safety levels; in this way, safety isolation of the multiple networks is guaranteed, and meanwhile efficient and reliable data unidirectional transmission can be achieved.

Description

technical field [0001] The invention relates to an image data network unidirectional physical channel efficient and safe introduction system and its application. Background technique [0002] At present, in order to prevent e-government, e-commerce and other secret-related information systems from leaking, the main measures taken are to prohibit the direct or indirect connection of secret-related information systems with low-class (or non-classified) networks, and physical isolation must be implemented. Although it is impossible for the information of the classified network to leak to the low-secret (or non-classified) network through the network after physical isolation, this is at the expense of the convenience of using the computer network, because the business systems running in the classified network Some of the required data inevitably comes from low-level (or non-classified) networks. After physical isolation, the required data can only be obtained manually by burning...

Although it is impossible for the information of classified network to leak to low-secret (or non-classified) network after physical isolation, this is at the expense of the convenience of using the computer network, because the business system running in the classified network Some of the required data inevitably comes from low-level (or non-classified) networks. After physical isolation, the required data can only be obtained manually by burning CDs, which greatly reduces work efficiency and affects the operation of business systems. real-time
