摘要
空天网络是天地一体化信息网络建设的重要组成部分,存在着网络高度暴露、节点高速运动、计算资源受限以及链路间歇连通等特点,给信息安全技术在空天网络的应用带来挑战,特别是节点的高速运动而带来的安全切换问题是实现节点可信保持、确保业务连续性的关键。在对空天网络切换分析的基础上,对空天网络节点的安全切换进行研究、分析与归纳,契合空天网络切换流程划分了安全切换的阶段过程,从切换感知、接入基站选择、切换认证等三个阶段阐述了当前的研究进展,给出了对比分析。最后对空天网络安全切换关键技术进行了总结,并对技术研究进行了展望。
The aerospace network is an important part of the construction of a space-ground integrated information net-work.It has the characteristics of high exposure of the network,high-speed movement of nodes,limited computing resources,and intermittent link connectivity,which pose challenges to the application of information security technology in the aero-space network.In particular,the problem of secure handover caused by the high-speed movement of the node is the key of achieving the credibility of the node and ensuring the continuity of the business.Based on the analysis of aerospace net-work handover,this paper studies,analyzes and summarizes the security handover of aerospace network nodes,and divides the phases of security handover according to the aerospace network handover process.The current research prog-ress is expounded from three stages of handover perception,access base station selection and handover authentication,and a comparative analysis is given.Finally,the key technologies of aerospace network security handover are summa-rized,and the technical research is prospected.
