Abstract :
A new two-dimensional chaotic system is proposed and is used in the secure communication in this paper. Because of the high Lyapunov exponent, complex chaotic signal and the nonlinear spread spectrum technology, it enhances the randomness and unpredictability of chaos carrier signals. Based on it, a new chaotic masking and encrypted method is developed. The simulation results show that the encryption effect is well, and the recovered information signal is less different from the original information signal. This system has the high safety performance and wide application.
