摘要
天地一体化信息网络由天基骨干网、天基接入网、地基节点网、地面互联网、移动通信网等多种异构网络互联融合而成,对实现国家安全战略目标具有重要意义。首先,介绍了天地一体化信息网络架构,以及卫星节点暴露、信道开放、异构网络互连等特征,并从物理层、运行层、数据层3个层面分析了天地一体化信息网络面临的威胁;其次,从物理安全、运行安全、数据安全3个层面对抗损毁、抗干扰、安全接入、安全路由、安全切换、安全传输、密钥管理等安全保障技术的研究现状进行了阐述;最后,针对天地一体化信息网络特点和安全保障需求,指出了天地一体化信息网络安全保障技术发展趋势和研究方向。
Space-ground integration information network consists of space-based backbone network, space-based access network, the node net of foundation, Internet, mobile communication network, which has important significance for the realization of the target of national security strategy. Firstly, the characteristics of space-ground integration network, such as exposed channel, heterogeneous network integration, etc, were analyzed. Also, the corresponding threats from the physical layer, operation.layer, data layer were introduced. Secondly, a comprehensive study on current status of survivability, anti-jamming, secure access, secure routing, secure handoff, secure transmission and key management were made. Finally, combined with research status, the important trends were proposed.
