Arnold变换与伪魔方变换在图像置乱中的研究

Research on Arnold transform and pseudocube transform in image scrambling

为了保证数字图像在网络上的安全传输,充分利用Arnold变换的简单易懂,以及伪魔方变换的安全性,文章对数字图像进行双置乱操作,使得加密的数字图像能够得到很好的隐藏,增加破解难度。结果分析表明,提出的方法能够保证秘密信息的安全传输,同时具有良好的抗攻击性。

In order to ensure the secure transmission of digital image on the network, make full use of the simple and easy to understand of Arnold transform, and the security of pseudo-cube transform, this paper carries on the double scrambling operation to the digital image. So that the encrypted digital image can be well hidden, increasing the difficulty of cracking. The results analysis shows that the proposed method can ensure the secure transmission of secret information and has a good anti-aggression.
