随着混沌理论的蓬勃发展，混沌系统的应用也日益广泛。混沌系统由于其独特的动力学特性，使得其非常适 合于图像加密。本文对混沌理论进行了阐述；对图像加密技术进行了研究；提出了混沌系统图像加密方法和基于混沌理论的 图像加密算法的设计。

The chaotic theory is booming, and the application of the chaotic system is also widely used day by day. Because of its unique dynamic characteristics, the chaotic system is very suitable for image encryption. The chaos theory is described. And the technology of image encryption is studied. The image encryption method of chaotic system and the design of image encryption algorithm based on chaos theory are proposed.
