Improving the Farnel Voting Scheme

Abstract

Farnel is a voting scheme which first introduced the concept of a ballot box to exchange votes. Recently, Araújo et al. improved this concept to accomplish a voter-verifiable scheme in which voters receive copies of receipts of one or more randomly selected previous cast votes. The scheme, however, relies on a strong requisite to achieve security: trustworthy talliers. With the goal of removing this requisite, in this paper we propose a Prêt-à-Voter style receipt for this scheme. In addition, we present a novel way to initialize the Farnel box and a new scheme based on combining Farnel with Prêt-à-Voter style encoding of receipts.
