In order to discuss the synchronization characteristic of a class of the cellular neural network and Lorenz hyper chaotic systems. This paper puts forward on the control method between different chaotic and dimensions system, using the controller and base on stability theory of Lyapunov to analysis of the synchronization stability. Finally a synchronization encryption algorithm for audio is presented as a new design. The simulation results show that there is not much correlation between the waveform of the audio document after it’s encrypted with that of the original one. By comparing the spectrum, it further testifies that the encryption effect of this design is remarkable.
