| Abstract: | A digital color image encryption algorithm is presented based on Arnold and Logistic Mapping.The traditional Arnold transformation is used on the image location scrambling.In addition the Logistic mapping is used to generate the chaos quenches that used on the image gray scrambling,so as to construct an algorithm combine both the position scrambling and the gray scrambling.The results of simulation by Matlab show that this algorithm can achieve good image encryption effect.And it has simple algorithm、the large key space、key sensitivity and many other advantages.It basically meets the effectiveness and security requirements of image encryption. |
