Abstract

In this paper, in order to facilitate the hardware implementation, the hyperchaotic Chen system is discretized based on the Euler algorithm, and the Lyapunov exponent is used to verify that it has the same hyperchaotic characteristics with continuous one. A nonlinear controller is constructed for synchronization of two discrete hyperchaotic Chen systems with the same structure, then the synchronization of it is proved by Lyapunov stability theory. Finally, the secret communication scheme based on nonlinear feedback synchronization is used to transmit the voice signal, which verifies the feasibility and efficiency of it again.
