【摘要】 基于巨型卫星星座的天基网络是未来指挥控制体系中的关键基础设施。然而,由于低轨卫星高速运行于复杂非受控的外太空环境,在对抗过程中易受攻击而导致瘫痪。文章围绕天基网络抗毁关键技术展开研究,分析了现有天基网络的抗毁能力;为实现星座损毁时天基网络服务的应急快速恢复,文章提出了面向天基动态网络的重路由机制和拓扑重构算法。仿真结果表明,所提抗毁技术能够保障在不同损毁场景下网络服务的快速恢复,满足指挥控制的时敏需求。更多还原

【Abstract】 Space information network(SIN) built upon mega-constellations is the key infrastructure for futuristic command and control systems.However,because low earth orbit satellites operate at high speed in a complex and uncontrolled outer space environment,they are vulnerable to various attacks.This paper focuses on the key technologies for resilient SINs.Specifically,we propose a rerouting mechanism,together with a topology reconstruction algorithm.The simulation results show that the proposed resilient technology can ensure the rapid recovery of network services in different damage scenarios and meet the needs of time-sensitive services.更多还原
