Secure communication via multi-parameter modulation using Chua systems

In this paper, a multi-parameter modulation scheme is proposed for secure communication via Chua chaos using an adaptive learning mechanism. It is proved that under the scheme, the tracking performance of the communication scheme can be guaranteed. It is also shown that by incorporating a low pass filter structure into the structure of the receiver, good tracking performance can be achieved. A microprocessor experimental study is provided to demonstrate the effectiveness of the method proposed.
