Abstract: In this paper, a novel high dimensional spatiotemporal chaotic system based on 2D non-adjacent coupled map lattice (2DNACML) model is proposed. Each local lattice is influenced by other random lattices in different dimensions and the local map is defined as a fractional-like style. From the theoretical analysis and numerical simulation, it is found that ranges of system parameters are expanded and unfixed in the novel 2DNACML model. As a result, the changed system is improved and been applied in the image encryption with a mixed scrambling scheme with chaotic method and knights tour method and an efficient diffusion scheme for different images to show the effectiveness of the proposed system.
