摘要
为了提高分数阶混沌序列加密图像的安全性,提出了序列互相关性和序列值的分布特性优化的Arneodo和Chen分数阶混沌系统。将优化后的Arneodo和Chen分数阶混沌系统应用于图像加密中,具体采用图像像素置乱和像素扩散的方法来进行图像加密。实验结果表明,优化后的Arneodo和Chen分数阶混沌系统序列互相关性和序列值的分布特性得到了明显提升,最终应用到图像加密中也得到了很好的加密效果。
In order to improve the security of encryption image of fractional-order chaotic sequence,purpose the Arneodo and Chen fractional-order chaotic system with optimized distribution character of sequence correlation and sequence value.Apply the optimized Arneodo and Chen fractional-order chaotic system in the image encryption,utilize the methods of image pixel scrambling and pixel spread to encrypt the image.Experimental results show that the sequence correlation and sequence value distribution character of optimized Arneodo and Chen fractional-order chaotic system have been significant improved,the excellent encryption effect has been realized in the obtained image encryption.
