Abstract：Image encryption is very important in protecting medical images. To solve the security problem of Arnold's periodicity,a method of combining Arnold and Knight's Tour algorithm is proposed. Firstly,an image is scrambled in an iterative process of Arnold. Secondly,it is cut into large and small areas,Lastly,it is scrambled by knight's tour algorithm locally and globally.The method enjoys the advantages of good scrambling and high security.
