摘　　要：高级在轨系统(AOS)主要用于满足复杂先进航天器测控、通信以及数据管理系统等方面的应用需求,为有效地进行交互支持、国际合作与交流提供了保证。基于AOS架构和典型应用场景分析了其所可能面临的安全威胁及其安全防护需求,针对AOS技术体制深入论证了各个安全防护层次的优缺点,对多级安全保护方案和密钥管理方案进行了比较深入的探讨,最后对我国AOS链路保护技术的研究和应用给出了初步建议。AOS system（Advanced Orbiting System） is mainly used to meet the application requirements in the complex monitoring of advanced spacecraft, communications and data management systems and ensure effective interactive support, international cooperation and exchange. Based on the typical architecture and application scenarios, the security threats and security protections AOS may face and require are analyzed. Furthermore, the advantages and disadvantages of each security level are demonstrated, and the multi-lev- el security protection schemes and the crypto key management schemes for the AOS technical system are discussed in-depth. Finally, some preliminary suggestions for the research and application of AOS link protection technology in China are proposed.
