| 摘 要： | Rijndael加解算法具有良好的安全性和高运行效率,被公认为较好的密码算法。针对数字图像数据量大、冗余度高、像素间相关性强的特点,将Rijndael算法中的轮密钥异或、S-盒变换、行移位变换和列混合变换应用在图像加密中,提出了基于Rijndael的图像置乱算法,主要实现了图像像素的像素值变换、图像像素的替换和图像像素的置换。实验结果表明,加密后的图像类似于白噪声的图像,达到了较为理想的置乱效果。

| Abstract: | Rijndael is famous for its high security and efficiency.According to the characters in the digital image field,there are huge data and high redundancy and strong relativity between the pixels,this paper uses Key Addition,S-boxShiftRows,MixColumns of Rijndael in the digital image encryption field,puts forward an image scrambling algorithm of based on the Rijndael.It completes transformation of image pixel,substitution of image pixel and re-arrangment of image pixel.The results show that: the encrypted image is similarly the white noise,to gain the good scrambling degree. |
