摘要：

This paper firstly discusses chaotic behaviors in a four-wing fractional-order system based on frequency-domain approach and time-domain approach, respectively. And chaotic dynamics is indeed found to exist in the system by numerical analysis. Then, in order to apply the system in secure communication, a new chaos circuit based on the four-wing fractional-order chaotic systems is designed to implement the synchronization mentioned. And the effectiveness and feasibility of the proposed synchronization scheme are verified by the new analog circuit. At last, an example of secure communication is given to show that the fractional-order four-wing system is appropriate for secure communication of some signals. (C) 2017 Elsevier GmbH.
