A Method for Digital Image Scrambling Based on AES
基于AES的数字图像置乱方法

With the security problem of image information as research background,this paper introduces the Advanced Encryption Standard(AES): Rijndael algorithm.Base on the symmetry block cipher algorithm,a method for scrambling and restoring digital images is proposed,which uses the AES algorithm under the control of secret key.This method is safe as well as simple.A simulation shows the effect of image scrambling,and it is analyzed by comparison of histograms.The results show that: this method can reach preferable effect of encryption and decryption,and further more,it's easy to realize.
