摘　　要：物理隔离是保护内部网络不受外网攻击的有效手段,这种隔离却严重影响了内网中业务信息系统的运行和用户的使用。为此本文提出了一种无反馈纯单向信息传输系统,该系统由外网服务器、内网服务器和单向传输通道三部分组成。阐述了系统的构成和工作原理,详细介绍了前向纠错方法、链路层设计和业务层结构等系统中的关键技术。分析了当信道误码率为10-5时,系统单向通信的误码率为6.3×10-24。该系统是一套完整的低密级网络到高密级网络的单向数据通信解决方案,具有安全、可靠、高效、便捷等特点,应用前景广阔。Physical isolation is an effective means for protecting inner network against outer network attacks, but it is harmful for the inner information systems and inner users＇ routines. A Non-feedback One-way Information Transmission System is proposed for solving this problem. The system is composed of a public server, a private server and a one-way transmission tunnel. The system＇ s construction and working principle are explained in this paper＇ s forepart. And the forward error correction method, link layer design and business layer structure of the system are discussed in detail. It＇ s analyzed that the system＇ s one-way transmission error rate is 6.3×10-24, when the chain error rate is 10-5. The system is a whole set of one-way solution that transmit data from non-confidence network to confidence network. This solution is safe, reliable, efficient and convenient with broad application prospect.
