摘要
文章提出了一种新的基于混沌的魔方置乱算法,并将其应用于图像加密。该算法借用了魔方变换的思想,通过混沌映射产生两列相互独立的魔方置乱参数序列,利用这些产生的序列在空域上对图像进行置乱。实验结果分析表明,该算法具有良好的保密效果,并能在一定程度上抵抗裁剪攻击和高斯噪声干扰。
A new magic cube permutation algorithm based on chaos is presented in this paper for image encryption.By employing the idea of magic cube transformation,this algorithm ulitizes chaos mapping to create two independent permutation parameter sequences of magic cube,then these produced sequences are used to permutate image in the space domain.The experimental results suggest that the algorithm proposed not only has a good ablility in encryption, but also can withstand the attack of tailoring and the effects of Gaussian noise to some extent.
