Research and realization of image encryption algorithms based on discrete chaos CAT
Xiao Wang · Informationization · 2009
Image encryption algorithm is of high iteration,low-key encryption-dimensional discrete chaotic space,and low privacy so we proposed CAT mapping to discrete images.The using of the map cyclical changes in the image is to be encrypted by different-sized images of different encryption cycle.Experiments show that,encryption algorithm can effectively encrypt images and obtain the best parameters to achieve the best image encryption effect.
