摘要
利用混沌序列的特性,提出了一种新的基于混沌序列的图像加密方法。首先由混沌序列生成变换矩阵对图像进行置乱处理,然后由另一个混沌矩阵对置乱图像逐像素以异或方式加密,最后将加密图像与目标图像进行线性融合得到最终的图像。
This paper presents a new method for image encryption based on chaotic sequences. At first,the original image is scrambled based on transformation matrix generated by chaotic sequences. Then the scrambled image is encrypted with another chaotic matrix by performing an exclusive OR (XOR) operation with each pixel one by one. Finally, the final image is obtained by linear image fusion of both the encrypted image and the object image.
