Abstract: A novel approach for generating binary chaotic sequences based on 4-D chaotic systems was proposed, and the performances of these binary sequences were analyzed. The proposed algorithm was compared with others as well. The results show that the generating binary sequences have good pseudo-randomness and correlation. The binary sequences were also applied to image encryption and good results were achieved.
