In this paper, the authors have discussed about image encryption based on chaotic algorithms. In recent years, a variety of effective chaos based image encryption schemes have been proposed. The typical structure of these schemes has the permutation and the diffusion stages performed alternatively. The confusion and diffusion effect is solely contributed by the permutation and the diffusion stage respectively. A number of image encryption algorithms based on chaotic maps have been proposed. Chaotic Key Based Algorithm (CKBA) is based on a one dimensional logistic map.
