A Practical Electronic Jury Voting Scheme

Electronic jury voting is a special E-voting which has only a few voters.Most previous E-voting schemes are not secure enough for jury voting because their final tallies are public to all voters and each ballot can be easily deduced from the result.Based on the improved secure-sum protocol and the private comparison protocol,a practical electronic jury scheme is proposed.By using the majority voting rule,the scheme only needs to determine whether the tally exceeds a pre-specified threshold while disclosing no additional information. This method satisfied requirement to enable an electronic jury,including privacy,dispute-freeness,receipt-freeness,etc.In comparison with the known schemes,our solution is more efficient in computation cost and communication cost and is easy to implementation.
