A Hyper-chaos Based Image Encryption Algorithm

摘要：

This paper presents a new image encryption algorithm, in this algorithm, shuffling matrix and diffusing matrix are generated based on Chens hyper-chaotic system. Firstly, the Chens hyper-chaotic system is used to shuffle the position of the image pixels, then use Chens hyper-chaotic system to confuse the relationship between the original image and the cipher image. The experimental results demonstrate that the encryption algorithm of image has the advantages of large key space and high security. Owing to more complex dynamical behaviors, the proposed encryption algorithm is more secure than some chaos based encryption algorithm.
