The Terminal's Application and Research of the Interactive Data Diode

S-With the advent of the era of global information, digitization, the network technology has penetrated into every corner of society. It has brought people's work and the study efficiency and convenience. But at the same time, from the point of the information security, network used widely also brought great information security hidden danger. Especially with classified information of some important departments and sensitive unit, they have requirements for data confidentiality. So rich resources and therefore cannot use the Internet effectively. In this paper, based on one-way transmission technology to realize the interactive connection system, the system can on the basis of pure one-way transmission meet the requirements of classified computer users active access to information, achieve on classified computer security for Internet access, browse and download files, and other functions, and on this basis, the future will be able to achieve more external information real-time one-way transmission function.
