Abstract

Lottery mechanism is a very popular activity since ancient times because of "luck" uncertain factor among the activities become full of fun. In recent years digital lottery behavior can be found anywhere, are the protocols upon which the scenario are based fair? Are the security mechanisms adequate to effectively prevent malicious behavior? They have long been much discussed. Online lottery system apply to wide scenarios, for example, a part of the a Game,or activities of the lottery which a large number of people to participate. If there is no one perfect and fair agreement to support electronic lottery situations, there will be no way to convince participants to trust the system, and thus unable to popularize and implement truly fair online lottery systems. Because of methods which adequately address the fairness and secure requirements of digital lotteries are lacking in practice. Sometimes the vast majority of lottery activities only require participants to trust the organizing officials. Based on lottery-type game events, this scheme first proposes a novel digital signature, which integrates the proxy signature and oblivious signature mechanisms. This signature protocol is then used to design a fair online lottery system. This system not only satisfies the fairness and safety secure requirements of a lottery, but also uses a proxy mechanism to improve the system’s overall efficiency. Finally, the system is implemented on a smart phone to provide the player with a more convenient digital experience while participating in game activities which take place in a truly fair environment.
