Abstract:

In this paper, a novel image encryption algorithm based on the chaotic modulation of Arnold dual scrambling combining with DNA computing is presented. This method can not only change the location of the image but can change the pixel values. First of all, we use the 2D-Arnold dual scrambling algorithm, which can disorder the location of pixels and pixel values at the same time. Secondly, we scramble the pixel values through the logistic chaotic sequence again. Then, we transform the digital image into DNA coding matrix based on DNA coding rules. Finally, we calculate with DNA sequence and the complement with DNA sequence by the new chaotic sequence. The experiment results and encryption effect demonstrate that the proposed scheme is effective, and it has strong sensibility, high security and good ability of resisting statistic attack.
