摘要： Arnold变换因其具有周期性，在图像加密方面得到了广泛的应用。但在解密过程中，若要利用其周期性，则显得很费时，因此提出了一种新的Arnold反变换算法。该算法通过求解方程组来求得反变换。

Abstract: Arnold transformation is applied widely in digital image encryption because of its periodicity.But if its periodicity is used in the course of image decryption，it will waste lots of time.So this paper offers a new anti-Arnold transformation algorithm.The algorithm gets anti-Arnold transformation by solving equation groups.
Key words: digital image, image encryption, image scramble, Arnold transformation
