A new image encryption scheme based on dynamic S-boxes combined with chaotic system is proposed. Different from traditional diffusion methods based on DNA operations, dynamic S-boxes composed of DNA sequences are used to diffuse the pixel values of the image. Simulation results and security analysis show that the proposed algorithm has good performance and ability to resist common attacks.
