Abstract :
In this paper, we present a new image encryption algorithm based on chaos system. First, deal with image using technique of permutation transform in image. Then, two-dimensional nonlinear map is utilized to circularly iterate gray value of pixels. The algorithm validly solves problem of failure of encryption owing to the self-similarity and visional physiological characteristic of image. At the same time, it remedies inadequateness of cryptological intension in other algorithms merely adopting permutation transform and have super security.
