Chaos may be degenerated due to finit precision effects, Therefore, in this study, a new compound two-dimensional chaotic function consists of two one-dimensional chaotic functions which are randomly created. A new chaotic sequences generator is designed by LFSR and the compound chaotic functions, which can generate very large key space. Image encryption algorithm is proposed based on diffusion and confusion by mapping 3D baker and dynamic combination chaos functions.
