A Novel Image Encryption Algorithm Based on Chaotic Sort

文章提出了一种新的基于混沌序列排序的混沌图像加密方法,其包含替代算法部分和置换算法部分,且两者都基于一维离散混沌映射。其中提出的混沌序列排序算法不仅提供的密钥空间大,而且置乱位置的随机性好,位置分布均匀。实验结果表明该算法具有很强的安全性。

In this paper,a novel image encryption algorithm based on chaotic sort is presented.The substitute algorithm and the permutation algorithm are based on discrete one-dimensional chaotic map.The permutation algorithm is provided with big secret key space,well randomicity and uniform distribution.Experimental results show that the proposed scheme has high security.
