A New Simple Algorithm for Scrambling

The paper proposes a new algorithm which use simple divisible and xor operation to change the values of pixels and the site of pixels in digital images based on logistic system. This algorithm encrypted images successfully. Experiments show that the algorithm is simple and easy to do. It has a large secret-key space and higher-security. Furthermore, the algorithm not only has preferable practicability, but also can resists various stacks.
