| Abstract: |
| The Internet of Things is the research hot spot, and clock synchroniza
tion is a key technology for Internet of Things. Internet of Things will involve
political, economic and military security, and the security of its clock synchr
onization has attracted much attention. Aimed at the lack of the research of clo
ck synchronization security, this paper presents a new algorithm for clock synch
r
onization security. Firstly,based on the idea of voting and feedback,the
course of this clock synchronization algorithm is given. Then,to solve the probl
ems 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 clo
ck synchronization algorithm can improve the security of the clock synchronizati
on. |
