A method of video encryption based on fractional hyperchaotic system was proposed.In order to weaken the correlation between pixels,firstly,the video stream was decomposed into images,then the position of images' pixels was scrambled by a cycle of algorithm.Secondly,the fractional hyperchaotic sequences of Chen system are used to encrypt the audio and video,so that the original video was encrypted effectively.Finally,we could use the key to decrypt the encrypted video.Simulations show that the method has a high efficiency and strong encryption security.
