中文摘要: 提出了一种新的基于魔方的混沌图像置乱算法。该算法基于魔方的循环移位的思想，把二维图像数据矩阵中的行或列中的若干个连续的像素值看作是一个二进制串，通过对该串的移位实现图像的置乱。而移位的次数则由混沌映射Logistic所产生的序列控制。实验仿真表明，该加密算法具有良好的加密效果，能有效地抵御各种外部攻击。
Abstract:In this paper, a new algorithm is proposed for image scrambling based on magic cube and chaotic. The proposed algorithm based on the idea of circulate shift regards some consecutive pixels in a row or a column in the image matrix as a group of bianry and scrambles the image by shifting these groups of bianry. And the number of shifting is controlled by the chaotic sequence generated by Logistic-map. Simulation shows that the proposed algorithm has good scrambling performance and can resist all kinds of attacks effectively.
