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.

基于有限时间混沌同步的基站与移动设备安全通信系统设计

本文提出了一种基站与移动设备之间的混沌安全通信系统。为了制作混沌键,移动设备和基站中使用了Chua混沌系统。混沌振荡器受到外部干扰和参数不确定性的干扰。基于Lyapunov稳定性理论和有限时间同步概念,设计了鲁棒终端滑模控制器。第一步,我们的目标是在有限时间内在外部扰动和参数不确定性下实现混沌同步。第二步,为了提高通信系统的安全性,提出了将混沌加密方法作为多移位密码加密和双混沌屏蔽相结合的方法。
