This paper therefore studies the digital image encryption scheme using cellular automata sequences combined with a chaotic system. Researh results reveal that the proposed algorithm that utilizes a combination of cellular automata & corresponding to the image entropy theory. The comparison of the before and after encrypted image each of bit planes correlation coefficient value are close to zero. The comparison between the original image and the encrypted image in terms of correlation shows that the correlation value is very close to zero , indicating that the encrypted image has high security.
