摘　　要：混沌系统有着复杂的动力学行为,采用复杂的8-涡卷蔡氏混沌系统,利用它的混沌特性,在驱动响应式同步的基础上,加入信号后再形成一个闭环和反馈,使驱动系统和响应系统达到同步的目的,以实现对数字图像的加密与解密.最后通过采用Matlab仿真软件,编写相应的加解密程序,给出了仿真的效果图.Chaotic system has complex dynamic behavior.A complex system of 8-scroll chaotic system was applied in which its chaotic characteristic was used.Based on the driven response synchronization,signals were added into and a closed loop and feedback in order to make drive system and response system achieve synchronization and to realize the encryption and decryption for Lena image.Finally,Matlab simulation software was used to compile corresponding encryption and decryption process and show out simulation figure.

关 键 词：图像加密 8-涡卷蔡氏混沌系统 驱动响应同步
