Abstract:

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 sch
 eme guarantees uniqueness, privacy,verifiability and fairness. Compared to the previous voting schemes, this scheme has a higher communication efficiency and security.
