无线传感器网络密钥管理技术在空间网络中的应用研究

Research on Application of Wireless Sensor Network Key Management Technology in Space Networks

现有空间网络密钥管理技术研究成果多数基于公钥密码算法,且对航天器硬件资源与通信能力受限、空间网络动态特性考虑相对不足;从工程应用可行性角度出发,在对空间网络密钥管理需求进行详细分析的基础上,将空间网络划分为小型星座网络、每个节点只有少数固定链路的星座网络、包含多个星座子网的空间网络以及ad hoc空间网络,对无线传感器网络密钥管理技术在各类空间网络中的应用进行研究分析,提出了工程上实用可行的空间网络密钥管理方案。

Most of the existing research results of space network key management technology are based on public key cryptography algo- rithm, and limited hardware resources, inadequate communication capabilities and network dynamics are not considered sufficiently. For better feasibility of engineering application, space network is classified into several stages, including small constellation network, constellation network that each node has only several static links, constellation network composed of several subnets and ad hoc space networks, and key management schemes for these kinds of space networks are proposed after summarizing space network key management requirements and ana- lyzing the application of current wireless sensor network key management technology in space network in detail.
