空间通信协议分析与一体化网络安全问题探讨

目前国际互联网体系结构及其协议虽然取得了巨大成功，但是当面对诸如长延时、多丢失、网络分区或节点生存周期短等环境时运行却不尽人意，尤其在缺乏基础设施或有限电源功率严格约束的空间环境下运行性能大为降低。文章在定量分析的基础上，讨论了空间通信网络的特点，对CCSDS的SCPS协议进行了简要综合分析，并且提出空间网络与地面网络互连时解决安全问题的一种可能途径。

Discussion of Data Security About Space-Earth All-in-One Networking and Analysis of CCSDS SCPS

The hugely successful architecture and protocols of internet operate poorly when faced with operating environments such as long delays, excessive loss, network partitioning, or short node lifetime. Such problems are typically found in extreme space environments which lack infrastructure or under severe constraints such as limited power. This paper primarily addresses characteristics of space communication network on the base of quantitative analysis, brief synthesis is performed for Consultative Committee for Space Data System(CCSDS) Space Communications Protocol Specification(SCPS), and a model accounting for data security problem of space-earth all-in-one networking is provided.
