A method of encryption is presented based on Logistic mapping image encryption method by using chaos theory. At first, the chaotic sequences are generated by Logistic chaotic map. Then, make the preliminary encryption combining with the original grayscale shift position disorderly. At last, make the simulation and analysis of experiment. The results show that the algorithm has large key space, quick speed and is easy to realize.
