摘　　要：该文针对在网络的不同安全域之间进行文件传输时数据只能由低密级网络向高密级网络传输的要求,设计了一款基于光的单向传输原理的数据单向传输系统,解决了利用通用移动存储介质将非涉密网络中的数据导入涉密计算机、同时防止涉密计算机中的信息通过通用移动存储设备泄露的问题。在硬件上设计上,由光单向传输特性保证数据单向传输;同时配合传输协议,通过限制和控制各节点带宽,保证数据传输效率和准确性。During the process of file transferring between different security domains, data have to be transmitted from the low level security network to the high level one. To meet this requirement, a one-way data transmission system based on optical fibre was designed to solve the problem of information leakage via general removable storage device during the process of importing data into the classified computer. On the hardware design, the one-way data transmission is achieved based on the light transmission property. The efficiency and accuracy of data transmission is guaranteed by limiting and controlling the bandwidth with the utilization of specialized transmission protocol.
