基于混沌映射的图像置乱加密算法

Image Randomly Encryption Algorithm Based on Chaos Mapping

提出了一种基于混沌映射的图像置乱加密算法,映射置乱了像素的位置,过程是可逆的,可用于加密图像.设计了密钥产生的方法,分析了图像加密算法的安全性问题.结果表明,该映射可加密压缩文件甚至任意长度的数据集.

A digital image encryption algorithm based on chaotic mapping is presented in this paper. The paper formulates the approach of the map,designs a method of key generation and analyses the security of the proposed image encryption. The simulation results show that the proposed encryption approach is valid. Analysis shows that the map can encrypt compressed images or arbitrary length of data sets.
