| Abstract: | A new modulo map is first presented and used in image location permutation in this paper.Because of the features of initial value sensitivity,parameter sensitivity,ergodicity and random sensitivity,now chaotic maps are widely used in information encryption.This paper put forward a image encryption algorithm based on modulo map and Logistic chaotic map.It's advantages include very huge key space and fast encryption and decryption process in the image encryption scheme. |
