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. %U http://cea.ceaj.org/EN/10.3778/j.issn.1002-8331.1610-0208
