Abstract:

We solve a long-standing challenge to the integrity of votes cast without the supervision of a voting booth: "it improper influence,‘’ which refers to any combination of vote buying and voter coercion. Our approach allows each voter, or their trusted agents, 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, 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 of security. Our system protects against the strongest adversary considered in prior related work and is suitable for widespread use in public elections.
