摘要
把二维图像矩阵堆积为三维矩阵,利用混沌序列具有容易生成,对初始条件敏感以及具有白噪声的统计特性等特点,提出了一种数字图象置乱方法:伪随机移位及函数处理的空间变换。该置乱方法在位置空间进行,具有随机性和变化的多样性,得出了较好的实验结果。
A new scheme of scrambling digital image is proposed by using the space transformation and chaotic sequences with good properties such as ease generation, sensitive dependence on initial values, and the statistic specialty of white noise. The proposed algorithm has the features of randomness as well as varieties for image scrambling, and a good encryption effect is achieved.
