Abstract:  

Abstract:  Welltried scrambling method is important to improve scrambling effectiveness, reduce key management cost and improve the resistance of attacking. In this paper, an image fundamental motion scrambling method was introduced. Firstly, image was divided into part A and part B; Secondly, the swap of pixels of part A and part B was implemented in uniform velocity motion method and pixels of part A was evenly distributed in part B; Lastly, image was scrambled by knighttour transformation in global and local view. The results of experiment show this method can decrease keys with good scrambling effectiveness and antiinterference performance.
