Abstract: On the basis of chaos theory,a gray-scale image encryption algorithm is presented.It generates XOR matrixes and replacement matrixes by using the Logistic Mapping,then divides the gray-scale image into pieces and encrypts them in turn.Experimental simulation shows that the encryption algorithm has a good effect of encryption.

摘要: 以混沌理论为基础,提出了一种灰度图像加密算法,该算法利用Logistic映射分别产生异或矩阵和置换矩阵,然后对灰度图像进行分块加密。实验仿真表明,该加密算法具有良好的加密效果。
