摘　　要：为了改进图像的加密效果,提出了一种基于高维猫映射的图像加密算法,先应用二维猫映射对图像的像素位置进行置乱操作,再采用三维猫映射生成的混沌序列对图像进行灰度置换和扩散操作。实验结果表明,该算法具有良好的安全性和加密效果。In order to improve the encryption effect of image, an image encryption algorithm is presented based on high dimensional cat map. Firstly, the two dimension cat map is applied to the scrambling operation on the pixel position of image. Based on this, the chaotic sequence generated by the three dimension cat map is used to gray permutation and diffusion operation. The experimental results show that the algorithm has good security and encryption effect.
