However, these developments have appeared independently and the two 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.} }
