| 摘 要： | 传统的Arnold变换能改变图像象素的位置,而不能改变图像象素值,不能仅仅靠Amold变换来实现图像加密.本文结合Logistic映射的伪随机性与对初值的敏感性,提出一种新的基于Arnold变换的图像加密算法,改进后的算法不仅改变了图像象素的位置,也改变了图像象素值.matlab仿真实验表明了该算法的有效性与安全性.

| Abstract: | Classical Arnold transform can change the position of image pixel points,but not the pixel value.It is obviously not enough to carry on the encryption by using the Arnold transform only.A new image encryption algorithm based on Arnold transform is proposed by exploiting the pseudo-randomness and the initial sensitivity of chaotic maps.The proposed schema changes the position and pixel value of the image.Simulated experiments show the security and the effectiveness of the algorithm. |
