Abstract: Based on the character of matrix M4 and circular shift,this paper advances a new algorithm.It can scramble a digital image quickly.From the histograms likeness and scrambling degree,experimental results indicate that this algorithm has faster and higher efficiency than others.

Key words: matrix M4, circular shift, scrambling

摘要: 讨论了M4矩阵的性质,然后根据图像像素值的特点,将0~255之间的数值分成不同的具有循环关系的集合。在此基础上,提出了一种利用M4矩阵和循环移位算法实现图像快速置乱的算法。实验数据表明,所提出的算法快速、有效,从直方图相似度和置乱度上都明显优于其他算法。
