Summary:This paper illustrates a multi-wing hyperchaotic attractors in coupled Lorenz systems. Novel four-wing hyperchaotic attractors are generated by coupling two identical Lorenz systems. Based on the Lyapunov stability theorem, this paper shows the synchronization between two identical hyperchaotic systems, the sufficient conditions for achieving the synchronization are derived. In addition, this synchronization is applied to secure communication through chaotic masking, using the chaotic signal to mask a continuous signal and a discrete signal. Simulation results show that the two systems can realize synchronization, further more, the information signal can be recovered undistorted when applying this method to secure communication.
