摘要
以图像信息安全问题为背景,介绍了高级加密标准(AES):R ijndael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。
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.
