This paper presented an image encryption scheme based on a three dimensional Jerk system.Firstly,the method preprocessed chaotic sequences from the Jerk system for better randomness.Then,used the sequences to shuffle the positions of image pixels.Finally,diffused the shuffled image by virtue of the chaotic sequences.And utilized the correlation of adjacent pixels to enhance anti-attack capability of the algorithm in decryption process.Simulation results indicate that the method has good effect of encryption and strong performance of security.
