Abstract:

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 surviv-ability, 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.

Key words: space-ground integration information network, security architecture, threats, security assurance
