中文摘要：
对空间信息网路由协议进行了研究,提出了一种基于GEO-LEO（geosynchronous earth orbit,GEO;low earth orbit,LEO）双层卫星组网的空间信息网抗毁安全路由协议.协议中GEO卫星组提供对LEO卫星的分组管理、密钥管理和超远距离中继服务功能,LEO卫星担任主要通信任务,路由消息采用对称密钥加密;协议在每个卫星周期时间片起始路由查找产生路由表并对该路由表进行存储,若在该卫星周期内没有卫星节点失效或链路拥塞的情况出现,路由表保持不变,否则触发路由更新过程.仿真分析实验表明,该抗毁安全路由协议在信令开销不大的情况下对空间信息网路由消息的可靠性和安全性有很大提高.
英文摘要：
Based on the study of routing protocol of space information network,an anti-damage routing protocol of space information network based on GEO-LEO has been proposed,and the detailed information of the protocol has been introduced.In the protocol,GEO satellites provide group management,key management and super long range relay for LEO satellites in groups.LEO satellites are mainly responsible for communications.Protocol information is enciphered through the symmetrical key.The protocol will use the router in the starting time of satellite cycle period to search for the routing table produced,and then save the routing table.If no satellite node becomes invalid and there is no network congestion,the routing table remains the same.Otherwise,the router will renew the routing table.According to the simulated experiment,the survivable routing protocol has greatly improved the reliability and the security of space network routing information when the signaling overhead is no high.
