摘　　要：提出了一种基于多维混沌系统的自适用加密算法,先从矩阵的某个元素开始遍历各个元素。根据图像的行的遍历顺序来决定的列的置乱顺序,再根据列的遍历顺序来对行进行置乱。然后使用三维Liu混沌系统对置乱后的图像进行加密。理论分析和实验表明,该方案具有良好的密码特性。An adaptive imagine encryption based on multidimensional Chaotic system is presented, firstly going through every element from certain element of matrix. Use the experience sequence of the image to decide the tier scramble of image, and use the tier sequence to decide the row scramble of image. Then Liu chaotic system is used to encryption the image by change the value of the pixel. Theoretic analyzing and the experimental result demonstrate that the image encryption algorithm shows the benign cipher characteristic.
