Abstract

This paper proposes a chaotic secure communication system between a base transmitter station and mobile equipment. To make the chaotic keys, the Chua chaotic systems are used in the mobile equipment and base transmitter station. Chaotic oscillators are perturbed by external disturbances and parametric uncertainties. Based on the Lyapunov stability theory and the finite-time synchronisation concept, a robust terminal sliding mode controller is designed. In the first step, we aimed to achieve chaos synchronisation under external disturbances and parametric uncertainties in a finite time. In the second step, to enhance security in the communication system, a combination of the chaotic encryption method as multi-shift cipher encryption and double chaotic masking has been suggested. The simulation outcomes are presented to show the applicability and performance of the proposed method.
