A combined image encryption algorithm was presented.The algorithm combined linear diffusion approach with Arnold mapped to disorder the image,and hyperchaotic sequences was used to encrypt the image.The mapped matrix and diffusion matrix were made up of chaotic sequences that were produced by the Logistic dynamic system,and they were used for disordering the color image to produce a disordered image on different bit planes to disorder the pixels.The disordered image was encrypted by means of the hyperchaotic sequences that were produced by the Chen's system.The algorithm is simple and able to resist a variety of attacks,and can be easily implemented by hardware.
