Abstract

Abstract: In order to increase the security of single chaotic systems, this paper proposesa new image encryption algorithm based on Chen chaotic system, cellular automaton and DNA. The 3-dimension Chen chaotic system is used to generate a pseudo random sequence. The DNA dynamic encoding on plain-text image and cellular automation is completed based on the transformed sequence. The DNA sequence of the plain-text image is divided into blocks, which arethen reorganized. These new groups of the DNA sequence of plain-text are combined with the DNA sequence of cellular automation to carry out the mixed operation with the cipher-text cross diffusion mechanism so as to get the final DNA sequence. The encrypted image is obtained by decoding the obtainedfinal DNA sequence. The simulation results show thatthe algorithm has the advantages of simple structure, high security and is easier to achieve, so it has great application prospects.
