摘　　要：提出一种基于双线性对的卫星网络密钥协商协议,分析卫星网络的特点,给出协议实现过程。对协议的安全性分析表明,该协议不存在密钥托管问题,能抵御主动攻击,会话密钥协商满足不可控性。对协议的性能分析表明,该协议能提高会话密钥协商效率,满足实际的卫星网络密钥协商需求。This paper proposes a key agreement protocol in satellite network based on bilinear pairings. It analyzes the characteristics of the satellite network and gives the implementation procedure of the protocol. Security analysis demonstrates that the key agreement protocol can resist active and passive attacks without key trusteeship problem and the key generating process is uncontrolled. Performance analysis demonstrates that the protocol can increase the efficiency of the session key agreement, it is more satisfied with needs of key generation in real satellite network.
