Abstract

In this paper, a new encryption algorithm is proposed for grey scale image. The proposed algorithm consist of two main stages: the DNA stage and the chaotic map stage. In the DNA stage, each pixel in plain image can be represented by four nucleotide bases by carrying out DNA coding and decoding to produce the plain image in DNA strands form. While chaotic stage exploits the Lozi Map, Logistic Map and Clifford system in keys generation to be used in the substitution, genetic recombination and permutation processes respectively. Accepted key space and sensitive key are gained by the proposed method, and the evaluation of the algorithm illustrate it has high effectiveness to resist exhaustive statistical attack.
