dc.description.abstract | We investigate the receipt-freeness issue of electronic voting protocols. Receipt-freeness means that a voter neither obtains nor is able to construct a receipt proving the content of his vote. [Hirt01] proposed a receipt-free voting scheme by introducing a third-party randomizer and by using divertible zero-knowledge proof of validity and designated-verifier re-encryption proof. This scheme satisfies receiptfreeness under the assumption that the randomizer does not collude with a buyer and two-way untappable channel exists between voters and the randomizer. But untappable channel is hard to implement in real world and will cause inconvenience to voters although it is provided. In this paper we extend [Hirt01] such that a tamper-resistant randomizer (TRR), a secure hardware device such as smart card or Java card, replaces the role of third-party randomizer and untappable channel. Moreover K-out-of-L receipt-free voting is provided in more efficient manner by introducing divertible proof of difference. | en |
dc.description.sponsorship | We would like to thank many anonymous reviewers for their valuable comments, which help to make this paper more readable one. There was a comment (and we agree) that the proof of difference may leak some information of voter’s vote, more than just the fact of difference. Further works need to be done to design more efficient ballot encoding and to improve the proof of difference. | en |
