摘　　要：针对无人智能终端普遍存在“重功能实现、轻安全防护”的问题,综合运用国密算法和安全协议,设计具备多终端安全交互能力的通信协议,实现身份认证、密钥协商、保密传输和防欺诈等安全防护能力。执行同一任务的两终端可通过三个报文完成身份认证、会话密钥协商和时间同步,而无需预先知道对方的身份信息,便于任务终端动态扩展。密钥协商运算基于椭圆曲线,具有比Diffie-Hellman密钥交换协议更高的效率和安全性。实验表明,协议适用于嵌入式处理器,安全运算对总体性能没有明显影响,较好地均衡了安全性与性能。It is common for unmanned intelligent terminals to attach importance to function realization and neglect security protection.By comprehensively using domestic cryptographic algorithm and security protocol,a communication protocol with multi terminal security interaction capability is designed to solve these problems.Security protection capabilities such as identity authenti⁃cation,key agreement,secure transmission and fraud prevention are achieved.Two terminals executing the same task can complete identity authentication,session key negotiation and time synchronization through three messages without knowing the identity infor⁃mation of the other party in advance,which is convenient for the dynamic expansion of task terminals.Key agreement is based on el⁃liptic curve,which has higher efficiency and security than Diffie-Hellman protocol.Experiments show that the protocol is suitable for embedded processors,and the security operation has no obvious impact on the overall performance,which better balances the se⁃curity and performance.
