外文摘要：Images, as a multimedia resource, for example, medical, education, sensing, and military images, have been playing an important role in digital in- formation communications. To prevent unautho- rized access and protect the security of all image, a direct approach is to encrypt the image [1, 2] to hide its information. Chaotic maps （systems） have some excellent inherent properties [3, 4], such as nonlinearity, sensitivity to initial conditions, and ergodicity. Therefore, they have received in- creasing attention and have been widely used in image encryption schemes. Tong et al. [5] pro- posed a hyper-chaotic system-based image encryp- tion scheme together with data compression.
