Abstract :
This paper proposed an image encryption algorithm based on 3D Lorenz chaos sequences. Firstly, the algorithm generates TWO sequences based on ranking two chaos sequences, and scrambles the position of color image. Then the RGB value of pixel of the scrambled color image is shuffled by the ranking of three chaos sequences, so the color encryption is realized. This results show that this algorithm has a large space of keys, high security and good privacy.
