چکیده
In this paper, four kinds of chaos mapping equations such as Logistic, Henon, Quadratic and MacKeyGlass were discussed, and the numerical characteristics of those chaos mapping equations were analyzed and compared by histogram and correlation coefficient. Then the better chaos encryption system was selected according to analyzing result, and the encryption method of poor chaos encryption systems were modified. So the good performance of encryption was obtained, the degree of image scrambling transformation was improved greatly, and good effect of image encryption was gained.
