摘要
列表签名是群签名的一个推广,对用户签名的次数作了有效限制并增加了公开检测和公开身份验证。本文基于列表签名提出可用于大规模选举的电子投票方案,任何人都可以对不诚实投票行为进行验证;若不诚实投票者投出超过一张的选票,则任何人都可以通过选票中的签名进行检测并确定不诚实签名者的身份。该方案同时保证了选票的唯一性、秘密性、可验证性和公平性,具有较高的通信效率和安全性。
List signature is an extension of group signature which has the additional functions of public detection and public identification. Based on the application in large-scale electronic voting systems advanced by the list signature scheme, anyone is able to check the dishonest voting behaviors. If a dishonest voter casts more than one ballot, anyone is able to check the identity of the dishonest voter through signatures from ballots. Meanwhile, this scheme guarantees uniqueness, privacy,verifiability and fairness. Compared to the previous voting schemes, this scheme has a higher communication efficiency and security.
