摘要
当非涉密网络向涉密网络导入数据时,如何保证涉密信息不会泄露到非涉密网络,是一个迫切需要解决的问题.数据二极管技术通过数据的单向传输来保证涉密网络的安全,但数据的准确传输仍是一个核心问题.提出一种扰码-冗余传输的方案来实现数据的无反馈稳定传输,并分析了数据稳定传输的概率.仿真实验表明该方案在损失一定有效通信带宽的情况下,能够在完全无反馈的传输系统中,将数据传输的容错率大大降低到工程可接受程度.
When transmitting data from non-secret network into secret network,it is very crucial to guarantee that the secret data could not be leaked out to non-secret network.The technology of data diode uses one-way transport to protect the security of secret network,in which the key problem is how to transport data accurately.In this paper an unidirectional transport method without any feedback is proposed using confusion and redundancy schemes,and the probability of data transport is also analyzed.Simulation experiments demonstrate that the proposed method can reduce the probability of data transport error with certain loss of communication bandwidth,however,which can be acceptable in engineering area.
