Abstract

To ensure the safety of image transmission,an image encryption algorithm based on improved chaotic map was proposed to solve the defects in traditional chaotic map encryption algorithms.The initial key was modified using Jacobean elliptic chaotic map to produce new key,and the key was processed using position method and was used to encrypt initial image.The simulation experiments were carried out to test the performance of algorithm.The results show that the proposed algorithm can obtain good encryption results and it has high security,huge key space.
