Cryptography is one of the most important ways of information security in passive defence. In this paper, a new image
encryption method using reversible and hybrid cellular automata is presented. Since four most significant bits of
each pixel have main information of an image, a hybrid cellular automata encrypts this bitst. Then, a reversible cellular
automata are applied to whole of the pixels and finally, cellular automata scrambles the image bits. Using a series of
standard tests, the suggested method was compared with some other methods to assess the efficiency of the algorithm.
The experimental results show that the suggested algorithm has satisfactory performance in terms of quantitative
assessment from some other schemes.
