摘要：

Based on the synchronization principle of three-dimensional discrete Henon chaos, this paper presents a new image encryption algorithm. A set of keys are generated by chaotic iteration from the sending part. Then the image can be encrypted. Via the same keys generated by chaotic synchronization, the receiving part can get decrypted image by inverse transformation. From the view of cryptology, high dimensional chaos in this paper is more complex than the general chaos, it is difficult to predict; and this algorithm can not only substitute the pixel values, but also scramble the pixel locations at the same time, but in most cases some algorithms can only encrypt the image in a way. As a supplement to the encryption process, this algorithm introduces the technology of chaotic synchronization and bits scrambling, increases the difficulty of cracking, and enhances the algorithm security. Simulation results illustrate the effectiveness of the proposed method. © Springer-Verlag Berlin Heidelberg 2014.
