In this work, we present a methodology of systematic design of an improved genetic algorithm (IGA)‐based secure communication in multiple time‐delay chaotic (MTDC) systems with advanced encryption standard (AES) and optimal H^∞ performance. To hide the message contents via chaotic signals, various approaches have been developed. Nevertheless, the attacks proposed in many studies have demonstrated that most of these approaches are not secure or have a low security. Therefore, in order to enhance the overall security, this work endeavors to combine chaotic synchronization with AES algorithm. The encryption method not only increases the strength of the communications system, but effectively protects the encrypted message as well. Finally, a numerical example is provided to show the achievements of this study.

混沌系统基于观察者的指数同步方案：使用高级加密标准作为辅助

在这项工作中，我们提出了一种改进的遗传算法（IGA）的系统设计的一个方法为基础的在多个时间延迟的混沌（MTDC）与高级加密标准（AES）和最佳系统安全通信ħ ^∞性能。为了通过混沌信号隐藏消息内容，已经开发了各种方法。但是，许多研究提出的攻击表明，这些方法大多数都不安全或安全性很低。因此，为了提高整体安全性，这项工作努力将混沌同步与AES算法结合起来。加密方法不仅增加了通信系统的强度，而且还有效地保护了加密的消息。最后，通过数值例子说明了本研究的成果。
