The development of the computer network makes image files transportation via network become more and more convenient.This paper is concerned with the image encryption algorithm design based Haircut Kits on the chaotic S-box mechanism.This paper proposes an Image Encryption algorithm involving both chaotic dynamic S-boxes and DNA sequence operation(IESDNA).The contribution of this paper is three folded: Firstly, we design an external 256-bit key to get large key space; secondly, we design a chaotic system to Cough-Cold And Flu Medications scramble image pixels; thirdly, DNA sequence operations are adopted to diffuse the scrambled image pixels.Experimental results show that our proposed image encryption algorithm can meet multiple cryptographic criteria and obtain good image encryption effect.
