The problem of chaotic color number image encryption is studied by using the encryption method of hybrid Lorenz chaotic system and Logistics map. Based on the Runge-Kutta methods, Lorenz system and Logistics chaos, a complex chaotic system encryption method is proposed. The method has multiple keys, and it has the advantages of multiple chaos, forming a strong security, which is suitable for color image encryption. Finally, the effectiveness of the proposed...
