To enhance the speed of image encryption systems and address the efficiency issues of dynamic S-boxes in practical image encryption applications, this paper proposes a fast image encryption method based on a novel one-dimensional chaotic map and dynamic S-boxes. The method introduces a new chaotic map to expand the parameter space of the encryption system, thereby strengthening the system’s resistance to exhaustive attacks. Additionally, dynamic S-boxes are used for nonlinear transformations of different pixel points, replacing the permutation...
