摘　　要：图像加密技术广泛应用于信息安全领域,并且在无线通信及互联网安全方面尤为重要。基于混沌保密通信原理,在单片机上采用CNN(细胞神经网络),实现了彩色图像的混沌保密通信。首先把彩色图像数据嵌入到混沌信号当中,然后在接收端根据混沌同步原理解出图像数据。给出不同噪声参数和同步参数时的实验结果,并对结果作简要讨论。Image encryption is widely used in information security, and plays an important role in the security of wireless communication and internet. Based on theory of chaotic secure communication, Secure communication of color image is implemented on MCU via CNN（Cellular Neural Network）. Firstly, the data of color image is imbedded in chaotic signal, and then is demodulated at receiver according to chaotic synchronization. Experiment results＇for different parameters, such as noise and synchronization, are given and discussed finally.
