Abstract:
The security of color image has become an important network information security research field. To meet the security requirements of color image and according to the characteristics of the image coding and chaotic system, the paper presented a color image encryption solution based on the chaotic systems. With the help of Logistic system, the solution generates the chaotic sequence, which is used to the parameters and the number of iterations of Henon system. And then, encrypt the color image through multiple iterating the Henon system. At last, we analyse and prove the solution in theory and experiment. The results show that the encrypted image has a uniform distribution of the pixel value, has a good solution diffusion, can effectively resist the phase space reconstruction attacks, and has a good security and reliability.
