چکیده
Due to the mature of networks and communication technologies, electronic commerce is growing up rapidly and many advanced applications in electronic commerce have been developed recently, such as on-line shopping, on-line bidding, and on-line gambling. There are numerous types of gambling like typical lottery, sport lottery, and poker gambling. Our research will focus on the lottery games. Owing to some special characteristics of the lottery games, such as fairness and anonymity, it is hard to design a secure electronic lottery protocol. The transaction mechanism in an electronic lottery protocol is an important issue since it will affect the benefits of customers if it is not fair or secure. Generating random winning tickets in a lottery game has been discussed in many papers, but the fairness and anonymity for purchasing tickets and claiming the prizes are only discussed in few papers and these previous results cannot completely cope with the problems of fairness and anonymity. In the paper, we propose an electronic lottery protocol that can achieve fairness and robust anonymity simultaneously.

متن کاملTowards Secure Quadratic Voting
We provide an overview of some of the security issues involved in securely implementing Lalley and Weyl’s “Quadratic Voting” [37], and suggest some possible implementation architectures. Our proposals blend “end-to-end verifiable” voting methods with anonymous payments. We also consider new refund rules for quadratic voting, such as a “lottery” method.

متن کاملComparing Sunspot Equilibrium and Lottery Equilibrium Allocations: The Finite Case
Sunspot equilibrium and lottery equilibrium are two stochastic solution concepts for nonstochastic economies. Recent work on nonconvex exchange economies has shown that when the randomizing device is a continuous random variable, applying the two concepts to the same fundamental economy yields the same set of equilibrium allocations. In the present paper, we examine economies based on a discret...
