On the Periods of Some Transformations Used in Digital Image Scrambling

摘要：

In this paper,the authors have analysized several transformation used in digitalimage scrambling,given some results on the periods of that transformation,Some notes on thetransformation when it is used have been proposed and the fast calculation method to these reversetransform.The results of this paper can make the computing complexity lower when the scramblingimage deciphered.
