Description: Due to the unpredictability and complexity properties, chaotic maps are widely applied in security, com- munication, and system control. Existing one-dimensional (1D) chaotic maps can be easily predicted and high-dimensional (HD) ones have more complex structures and higher computation costs. In order to enhance the chaotic performance, this paper proposes a new two-dimensional infinite collapse map (2D- ICM). Compared with existing 2D chaotic maps, 2D-ICM has better ergodicity, hyperchaotic property, un- predictability, and a wider chaotic region. To investigate its application, we further propose an image encryption algorithm using 2D-ICM. Simulation demonstrates that the proposed image encryption algo- rithm has excellent performance for protecting various kinds of images.
