Image encryption based on a new total shuffling algorithm

This paper presents image encryption scheme, which employs a new image total shuffling matrix to shuffle the positions of image pixels and then uses the states combination of two chaotic systems to confuse the relationship between the plain-image and the cipher-image. The experimental results demonstrate that the new image total shuffling algorithm has a low time complexity and 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 image has a random-like behavior.
