【摘要】 混沌序列具有易生成性,对初始条件强敏感性,可完全重现性等特点,基于以上特性提出了一种基于混沌序列的图像置乱算法。算法中同时采用Logistic映射和Hybird映射,将其产生的二值序列分别与数字图像的奇行和偶行采用异或置乱算法对图像进行置乱。模拟实验证明该算法实现简单,安全性很高,对椒盐噪声和剪切有一定的抗攻击性。更多还原

【Abstract】 Based on Chaotic sequences,a new digital image scrambling algorithm is presented.XOR scrambling algorithm based on Logistic mapping and Hybird mapping is used to scramble the image,odd-numbered lines XOR two value sequences produces with the Logistic mapping,and the even-numbered line XOR the Hybird mapping produces two value sequences.The simulating experimentation shows that the algorithm is simple,security very highly,and has certain anti-aggressivity to the salt & pepper noise and shears.更多还原
