| 摘 要： | 以图像信息安全问题为背景，介绍了高级加密标准（AES）：Rijndael算法，并在此对称分组密码算法的基础上，提出了密钥控制下采用AES算法进行图像置乱与恢复的方法。该方法既安全又简便。实验结果显示了图像置乱的效果，通过直方图的比较对此进行一定的分析，结果表明，这种方法能达到较好的加密与解密效果，而且易于实现。

| Abstract: | 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. |
