Abstract : The cryptographic foundations of e-auction and e-voting schemes are similar, for instance, seminal works in both domains have applied mixnets, homomorphic encryption, and trapdoor bit-commitments. However, these developments have appeared independently and the two research communities are disjoint. In this paper, we demonstrate a relation between e-auction and e-voting: we present Hawk and Aucitas, two e-auction schemes derived from the Helios and Civitas e-voting schemes. Our results make progress towards the unification of the e-auction and e-voting domains.
Keywords : Hawk Helios Price flexibility Privacy Sealed-bid Verifiability Voting Auction Aucitas Bid secrecy Civitas Collusion resistance
