Abstract

Chua’s circuit, which is improved to integrate conveniently, is presented. A drive-response chaotic synchronization system is constructed, which possesses a certain stability, resisting-disturbance, and so on. By means of research, it can be concluded that the chaotic synchronization system is provided with the characteristic of chaos synchronization self-maintenance. Utilizing the characteristic, the critical problem of how to simultaneously transmit the controlling signal of chaotic synchronization and the secret signal at a channel can be solved, and that a practical experiment validates the method; as a result, the research in the paper provides the foundation of putting chaos into practice application to secret communication.
