Abstract: Random number generation is important in e-commerce, especially in the situation that the fairness is the basic requirement. Moreover, due to the fact that many protocol is executed in the mobile device, the lightweight is vital to the practice environment. In this paper, a novel random number scheme is presented using the one-way function, which guarantees two entities to be equally involved in the result generation, in addition, it is fair, efficient, security, practical, forgery-resistant, and unpredictable.

Key words: one way function, random number, verifiable, fairness
