Abstract
We solve a long-standing challenge to the integrity of votes
cast without the supervision of a voting booth: “improper influence,”
which we define as any combination of vote buying and voter coercion.
Our approach allows each voter, or their trusted agent(s), to cancel their
vote in a way that is unstoppable, irrevocable, and forever unattributable
to the voter. In particular, our approach enhances security of online, remote,
public-sector elections, for which there is a growing need and the
threat of improper influence is most acute. In this extended abstract,
we introduce the new approach, compare it with previous methods, and
concisely summarize the protocols. In our full paper, we give detailed
cryptographic protocols, show how they can be applied to several voting
settings, describe our implementation in a full voting system called VoteXX,
and provide UC proofs. Our system protects against the strongest
adversary considered in prior related work and is suitable for widespread
use in public elections.
