摘　　要：以图像信息安全问题为研究背景,讨论了三维Arnold逆变换和n维Arnold逆变换的周期性,给出了周期的上界估值定理,并用实例说明了三维Arnold逆变换在数字图像置乱中的应用。With the research background of image information security, the periodicity of Arnold contrary transformation of three dimensions and n dimensions is discussed in the article.A theorem is given to estimate the upper bound of the periods. The function of the three dimensions Arnold contrary transformation in digital image scram bling is proved by experiment.
