In the above method, it is this that one-way isolation channel, which is realized by the two dimensional code channel isolation of independent development, The core of method.Coded treatment list is established in the uni-directional physical channel isolation transmitting terminal host system being connected with network A Member, coding processing device, network interface;Solution is established in the uni-directional physical channel isolation receiving end host system being connected with network B Code processing unit, decoding processor, network interface.Eye recognition equipment is simulated by display screen and camera and sends end main frame system System, receiving end host system composition.Display screen is connected with transmitting terminal host system, and video camera is connected with receiving end host system, After data are carried out two dimensional code coding by transmitting terminal host system, shows, after video camera grabs two dimensional code, will count on a display screen According to the decoding of receiving end host system is sent to, receiving end host system again goes out data forwarding.Do not appoint in one-way isolation channel The connection of what physics, this guarantees physical isolations and blocking that data are transmitted between intranet and extranet.Meanwhile one-way isolation channel limits It has made receiving end host system and has sent data without normal direction transmitting terminal host system, thus reduced transmission end main frame to greatest extent A possibility that system is under attack.
The transmitting terminal host system, receiving end host system are two sets of independent system boards, be respectively owned by from Oneself CPU, operating system, memory and bus, between two systems other than one-way isolation channel and there is no any straight It connects or indirectly contacts.Coding side receive file send client send data, by two dimensional code coding module to data into Row coding, and by the image after coding channel isolation display screen display.Decoding end is caught by the video camera of channel isolation Image in 2 D code is caught, image data decoding is verified, after being reduced into initial data, sends data to file reception server.
Above-mentioned unidirectional transmission property is that coding side can only send data by display screen, and decoding end can only pass through camera shooting Machine receives data, and centre only has channel isolation.One-way isolation channel is complete physical isolation, intermediate no any line, one Aspect ensure that the one-way of transmission, on the other hand ensure that the mode of data transmission can only be transmitted by way of two dimensional code.
The fault tolerant mechanism of QR (fast reaction) the two dimensional code coding carries out QR coding in transmitting terminal host system, raw At image in 2 D code not only contained initial data but also contain fault tolerant data, decoding end is not only able to find wrong symbol, and And error correction can be carried out to wrong symbol.
The time data recovery mechanism of the fountain coding carries out fountain coding to initial data in transmitting terminal host system, Redundant data is added, improves data recovery capabilities of the decoding end in the case where losing data cases.
The data compression scheme of lz4 (compression algorithm) coding, lz4 Compress softwares speed with higher can be very Good support multi-thread environment, compressed data can save the bandwidth of network, improve efficiency of transmission, and can verify to data.
