This paper presents a new approach for image encryption based on a Liu fractional-order hyperchaotic system and a new hyperchaotic system. Use two of the four sets of hyperchaotic sequence generated from the Liu fractional-order hyperchaotic system to scramble the original image pixel position and two of the four sets of sequence generated from the new hyperchaotic system to replace the pixels for the purpose of encryption image. Then simulation results show that the approach proposed has good encryption efficiency.
