The Delta-modulated complex dynamical systems has abundant evolvement behaviors.If its parameters in the confined range,the system produce chaotic sequence with good performance in pseudo-randomicity,ergodicity and sensitivity to initial values.Research of image encryption based on delta-modulated complex dynamical system is presented.The experiment shows that it has property of key sensitivity,high key space.The method has satisfies security to image encryption.
