Image Encryption Schemes Based on a Class of Uniformly Distributed Chaotic Systems

This paper proposes a method to construct one-dimensional discrete chaotic system. First, we define generalized distance function control the boundedness of Based on Marotto’s theorem, systems are proven be in sense Li–Yorke, and corresponding chaos criterion theorem is proposed. The system can distributed uniformly by adjusting parameters. In this paper, propose an image encryption scheme based DNA encoding. encoding decoding rules determined plain text. experimental results demonstrate that our algorithm has large key space, high sensitivity, fast speed resist differential statistical attacks.
