ABSTRACT
In this paper, we suggest one compound chaos image encryption method with time- varying multilevel initial parameters. This algorithm combines Subsection-linearity mapping, Chebyshev mapping with Logistic mapping in order to disturbing values of each image point and the array of original images based on chaotic second-scrambling way. The chaotic system uses time-varying system clock to change the first chaotic mapping initial parameter, and takes those chaotic sequences which generated by the first chaotic mapping as the initial parameters for the second chaotic mapping, then generate two-dimensional image pixel position scrambling matrix, and uses the same system clock to lock Chebyshev mapping initial parameter, then generate two-dimensional image pixel value transforming matrix. By this way for using the time-varying system clock, The encryption system can randomly changes many initial parameters of chaotic image encryption system to enhance image transmission security, has the capability of “one time one secret”. The simulation results show that this algorithm is simple, safe, easy to achieve with software and has huge secret key space.
