ABSTRACT
The development of a new image encryption algorithm using real structures of deoxyribonucleic acid (DNA) molecules is considered. In the proposed algorithm, the encryption process is performed by confusing and rearranging the pixels of the image based on the coordinates of the chaotic points obtained by the chaos game of DNA symbols, the sequence of DNA symbols, and the encoding rule.We propose a new image encryption algorithm based on DNA sequences combined with chaotic maps. This algorithm has innovations it diffuses the pixels by transforming the nucleotides into corresponding base pairs a random number of times. For any size of the original grayscale image, the rows and columns are fist exchanged by the arrays generated each pixel that has been confused is encoded into four nucleotides according to the DNA coding each nucleotide is transformed into the corresponding base pair a random number of time(s) by a series of iterative computations.
