Device and method for implementing data transmission between physical isolation networks based on hexadecimal codes

Abstract

The invention relates to the technical field of network information security exchange, in particular to a device and method for implementing data transmission between physical isolation networks based on hexadecimal codes. The device comprises a data source computer, a display screen of the data source computer, an image acquisition device and a target computer. The data source computer and the target computer are located in two networks in the physical isolation state respectively. A data source generation module is arranged in the data source computer to convert source data into multiple sets of data embedded with serial numbers, secret keys, effective data marks and screen display rules, and the data are sent to the display screen in a split screen mode and displayed in the form of hexadecimal code characters. The image acquisition device acquires images displayed on the display screen and transmits the acquired images to the target computer, a parsing module in the target computer identifies and parses the images, the parsed information is decoded, combined and uncompressed, and then data consistent with the source data are obtained. By means of the device and method, data transmission between the two networks in the physical isolation state can be conducted in real time, synchronously and automatically, and meanwhile, data transmission is safer and more reliable.

Description

technical field [0001] The invention relates to the technical field of network information security exchange, in particular to a device and method for realizing data transmission between physically isolated networks based on hexadecimal codes. Background technique [0002] With the in-depth development of information technology, viruses and hackers seriously threaten the security of computer information systems. In order to prevent computers and information systems involving state secrets from being attacked by public information networks such as the Internet, on January 1, 2000, the State Security Bureau implemented the "Regulations on the Administration of the Secrecy of International Networking of Computer Information Systems". Secret computer information systems must not be directly or indirectly connected to the Internet or other public information networks, and must be physically isolated. [0003] The implementation of physical isolation between the internal network ...
