| Abstract: | E-lottery is a popular game for its convenience provided by the Internet. An e-lottery scheme based on voting is proposed. The scheme is publicly verifiable and the fairness can be guaranteed. Lottery players not only provide seed numbers to create the initial value of the lucky number, but also have an opportunity to change the intermediate value of the lucky number by means of voting. The new property of the scheme makes the lottery game more interactive and attractive to players. The anonymity of submitting the lottery ticket and casting the vote is achieved. Comparison with other existing e-lottery schemes is given. |
