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. supersededby: - key: 2015-election-to-auction-transform text: journal article links: - file: Smyth14-Hawk-and-Aucitas-auction-schemes.pdf text: Conference paper - file: Smyth14-Hawk-and-Aucitas-auction-schemes.long.pdf text: Extended version - file: Smyth14-Hawk-and-Aucitas-auction-schemes.code.tar.gz text: Hawk source - url: https://doi.org/10.1007/978-3-662-45472-5_4 text: Official version
