空间信息网络安全协议综述

Survey on Security Protocol of Space Information Networks

针对空间信息网络安全协议展开综述。首先介绍了建设空间信息网络安全的意义,其次论述了国内外对空间信息网络安全协议的研究现状,然后重点对空间通信协议规范-安全协议(SCPS-SP)的核心关键技术——认证及加密算法进行详细分析。在此基础上,指出SCPS-SP在应用过程中遇到的挑战,并给出解决的思路和相关的建议。

This paper summarized the space information network security protocol.Firstly,we introduced the significance of construction of space information network security.Secondly,we discussed the research status at home and aboard of the space information network security protocol.Then we analyzed authentication and encryption algorithms in detail,which are the key technologies of space communication protocol specification-security protocol（SCPS-SP）.On this basis,we indicated the challenges which SCPS-SP faced in the application,and gave some ideas and suggestions for solution.
