Design and Implementation of Network Information Security One-way Transmission

Due to viruses and hackers are becoming increasingly rampant leaks gradually increased, the paper designed a network information security and one-way transmission system which based on single-fiber one-way multi-mode fiber. In hardware design, one-way transmission system based on single-fiber one-way multi-mode fiber and using optical transmitter and optical receiver to achieve one-way transfer card. In software design, proposed a "push" and "pull" two kinds of data transmission to achieve the stability of no feedback-free transmission technology. The one-way transmission system that is possible to obtain information from low-Security Level Network can prevent high Security Level network information disclosure, improve the exchange of information between the network securities.
