Abstract
Nowadays the whole world is upgrading with different innovative technologies. We need to resist any attack during data transfer over insecure networks. Random nature & sensitivity to initial conditions in dynamical maps are highly useful to secure cryptography algorithms. In this paper, structure of different chaotic maps have been reviewed, basis of chaos-based image encryption has mentioned. Finally a new encryption scheme has been proposed using tent & logistic map. Performance analysis of proposed scheme has been discussed. Different coupling of chaotic maps, aspects of elliptical curve can be considered for compressed image, video or audio encryption as future work.
