Abstract

To obtain a more secure colour image cryptosystem without complex construction, this paper presents a general simple colour image encryption model with a very high level of security, and that is based on two nearby orbits of chaotic systems. First, the initial value of a one-dimensional (1D) chaotic map is obtained using plaintext. Then, we obtain two nearby orbits of 1D chaotic maps to generate three new chaotic signals. Next, the generated systems independently encrypt the red, green and blue components (RGB) of the colour image. Finally, the three encrypted images are combined to obtain the final encrypted image. Simulation results show that our method is simple, effective and passed all NIST tests and part of TestU01 test. Since the proposed method is related to plaintext, it has much higher security level compared with the most recently reported chaos-based image algorithms. More importantly, the 1D logistic cryptosystem based on our method has a large key space with higher security.
