摘要
针对低维混沌系统结构比较简单、易受攻击等不足,提出一种新的基于六维超混沌系统的图像加密算法.首先利用六维超混沌系统产生一组混沌序列;其次基于混沌序列和循环移位完成图像的置乱操作;再次基于混沌序列和DNA编码完成图像的扩散操作;最后根据DNA解码规则完成图像解码,进而实现图像的加密.经过实验验证,该算法密钥空间大,复杂度高,加密效果好.
Abstract
A new image encryption algorithm based on a six dimensional hyperchaotic system is proposed to address the shortcomings of low dimensional chaotic systems,such as their simple structure and susceptibility to attacks.Firstly,a set of chaotic sequences is generated using a six dimensional hyperchaotic system.Secondly,the image scrambling operation is completed based on chaotic sequences and cyclic shifts.Once again,the image's diffusion operation is completed based on chaotic sequences and DNA encoding.Finally,the image decoding is completed according to the DNA decoding rules,thereby achieving image encryption.After experimental verification,the algorithm has a large key space,high complexity,and good encryption effect.
