| 摘 要： | 针对传统数字图像置乱算法需多次迭代、加密强度不够、密钥空间小和抗攻击性差等问题,基于混沌序列提出一种新的数字图像置乱算法,该算法借助于进制转化和移位改变数字图像的像素值和像素位置,从而使人们无法识别原始图像所表达的真正含义.理论分析和实验结果表明:该算法具有较大的密钥空间,无需迭代,对密钥有很强的敏感性,能改变图像的灰...

| Abstract: | In general,classical image scrambling algorithms exist some problems such as needing many iterations,insufficient strength of encryption,little key space,weak resistance.Based on the chaotic sequences,a new digital image scrambling algorithm was proposed.By making use of the system transformation and shifting to change pixel values and position simultaneously,the true mean of original image can not be found.Theory and experimental results show that the new algorithm has large key space and does not involve ... |
