The experimental research of chaos-based secure communication based on drive-response synchronization method

In this paper, we talked about the method of chaotic synchronization. Basing on the drive-respond synchronization method presented by Pecora and Carroll, we realized the chua´s chaotic circuit. A theoretical analysis is made for the feasibility of encryption communication by using chaos, and designed experimental circuit of chaos-based secure communication. The experimental results indicated that: when ƒ ≥ 8kHz, the effects of encryption and decryption are good. The research result in this paper laid a theoretical foundation for the further research work.
