In order to improve the security of image encryption algorithm,a new image encryption algorithm based on chaotic theory is proposed in this paper.Firstly,the original image is decomposed into R,G,B components,and then R,G,B components of original image are encrypted by different chaotic systems,finally,the encrypted R,G,B components are combined to get the encrypt image,and simulation experiments are carried out to test the performance of encryption algorithm.The simulation results show that the proposed encryption algorithm can increase key space and enhance anti attack capability,and can acquire very good encryption effect and can protect the safety image very well.
