| 摘要: |
| Arnold 变换由于具有周期性，被广泛地应用于图像加密。但在利用其周期性进行解密时，有时会比较费时，因此提出了一种Arnold 逆变换算法；在此基础上，将其拓展到非方阵图像，即一般的矩阵图像上，扩展了其在图像加密上的应用范围；最后在理论上将二维推广到n维Arnold变换及逆变换。 |

| Abstract: |
| Arnold transform,due to its periodicity;is widely used in image encryption,however,it is quite time-consuming when the periodicity of the transform is used in decryption,as a result,anti-Amold transform algorithm is presented… |
