Abstract: An adaptive image encryption algorithm based on Lorenz system is put forward.Firstly,scrambling algorithm of  the original image was achieved by adaptive algorithm,then the image was substitution encrypted based on the Lorenz chaotic system.The experiment results showed that the algorithm has stronger resistance to exhaustive and statistical attacks,and it is of high security.

Key words: Lorenz system, image encryption, substitution, scrambling
