基于混沌映射和DNA编码的图像加密算法
Image encryption algorithm based on chaotic map and DNA coding
摘要
Abstract
In order to improve the efficiency and security of image encryption,an image encryption algorithm based on chaotic map and DNA sequence is proposed,which is based on the analysis of the existing image encryption algorithms. First of all,adopting the chaotic mapping to generate chaos sequence of image scrambling in bit-plane and to achieve the dual effect of encryption,image scrambling and diffusion.Then using the DNA encoding rules to code after scrambling image with DNA computing and to realize the diffusion of the image.The experimental results indicate that the key space of the proposed algorithm is large enough,the key sensitivity is strong,and it has better security.关键词
