Secure communication based on the synchronous control of hysteretic chaotic neuron

In order to improve the physical realization of the chaotic secure communication, a chaos masking encoding method based on the synchronous control of chaotic neurons with different structure is proposed. The conventional chaotic neuron is set as the transmitting system, and the hysteretic chaotic neuron is set as the receiving system. Hysteretic parameters have creep characteristic which make the hysteretic chaotic neuron have uncertainty. Sliding mode control is used to perform the synchronous control, and fuzzy inference is used to reduce the chattering of the sliding mode control. Simulation results prove the effectiveness of the method.
