Prêt à Voter with Confirmation Codes

A scheme is presented in which a Pretty Good Democracy style acknowledgement code mechanism is incorporated into Prêt à Voter. The idea is to provide voters with an immediate, and usable, confirmation at the time of casting of the correct registration of their receipt on the Web Bulletin Board. As with PGD, the registration and revelation of the confirmation code is performed by a threshold set of Trustees. Verification of the registration of the vote is now part of the vote casting and therefore more immediate and convenient for the voters. The scheme presented here is thus more convenient while maintaining the level of verifiability of conventional Prêt à Voter. It also means that we are less reliant on the diligence of voters in later performing checks on the Bulletin Board. It seems probable that this confirmation code mechanism will provide voters with greater confidence that their vote will be accurately tallied.
