摘　　要：针对物联网时钟同步安全研究的不足,提出了一种时钟同步安全算法。首先,基于投票竞争的理念,给出了时钟同步安全算法过程;然后,为了解决此过程中涉及到的网络通信延迟不确定难题,提出了基于D-S理论的解决方法;最后,进行了仿真测试实验,结果表明在网络通信延迟不确定情况下,所提同步算法能容忍内部节点攻击,提高了时钟同步的安全性。The Intemet of Things is the research hot spot, and clock synchronization is a key technology for Internet of Things. Internet of Things will involve political, economic and military security, and the secunity of its clock synchronization has attracted much attention. Aimed at the lack of the research of clock synchronization security, this paper presents a new algorithm for clock synchronization security. Firstly, based on the idea of voting and feedback, the course of this clock synchronization algorithm is given. Then, to solve the problems caused by communication delay in algorithm process, a solution based on D - S theory is proposed. Finally, the test experiment is performed and the results show that the proposed clock synchronization algorithm can improve the security of the clock synchronization.
