摘要
基于比特承诺,给出了一种无需可信第三方的电子彩票方案。该方案不要求购买者在线,不对购买者的计算能力做出苛刻限制,不要求可信第三方参与。该方案具有不可伪造性,公平性,公开验证性等特点。该方案还与传统彩票有良好的兼容性。
Based on bit commitment, this paper designs an e-lottery scheme which does not involve a trusted third party. This scheme does not assume all the purchasers are online. It overcomes the limitation of the purchasers＇ computing power and does not need to involve a trusted third party. There are many security properties in this scheme, such as unforgeability, impartiality, publicly verification and so on. This scheme also maintains compatibility with the traditional lottery.
