An Anonymous Electronic Voting Protocol with the Latest Decision on Voters' Intentions

In most of the anonymous electronic voting schemes presented in the literature, every voter must decide his intention for a voting before the tally center performs the signing operation on his vote. In these schemes, voters cannot modify or update their intentions embedded in the signed votes even if they have not been sent to the tally center for tallying yet. This paper presents a new anonymous voting protocol to cope with the problem such that voters do not need to determine their intentions until their votes are to be submitted to the tally center for tallying. Our method can be implemented on the electronic voting schemes in the literature to delay the intention decision for voters without affecting the infrastructures of these schemes, and the additional computation is just hashing.
