A new image encryption algorithm based on hyper-chaos. (English)
[J] Phys. Lett., A 372, No. 4, 394-400 (2008). ISSN 0375-9601

Summary: This Letter presents a new image encryption scheme, which employs an image total shuffling matrix to shuffle the positions of image pixels and then uses a hyper-chaotic system to confuse the relationship between the plain-image and the cipher-image. The experimental results demonstrate that the suggested encryption algorithm of image has the advantages of large key space and high security, and moreover, the distribution of grey values of the encrypted $y$ image has a random-like behavior.
