This paper presents a novel image encryption scheme based on the Arnold mapping and the Logistic mapping.First separated the three channels of a RGB mode image,then transformed them into 3 two dimensional grey images.We respectively scramblinged these gray images of the three colour channels or changed their gray value by different methods,we finally combined the three ciphertext into a RGB mode image.The results of experiment simulation show that the algorithm is valid and has good performance.
