Delaying function refers to a type of function where the output of the function requires some time, with computational complexity different from cipher. This paper gives a method of realizing delaying function based on hash collision and the delaying function realized by this method is characterized by safety, high-efficiency and controllable delay. This approach can be applied to the generation of winning numbers of e-lottery ticket, which is beneficial for the design of e-lottery scheme.
