Coercion-Resistant Hybrid Voting Systems

This paper proposes hybrid voting systems as a solution for the vote buying and voter coercion problem of electronic voting systems. The key idea is to allow voters to revoke and overrule their electronic votes at the polling station. We analyze the potential and pitfalls of such revocation procedures and give concrete recommendations on how to build a hybrid system offering coercion-resistance...

Coercion Resistant End-to-end Voting

End-to-end voting schemes have shown considerable promise for allowing voters to verify that tallies are accurate. At the same time, the threat of coercion has generally been considered only when voting devices are honest, and in many schemes, voters can be forced or incentivized to cast votes of an adversary’s choice. In this paper, we examine the issue of voter coercion and identify one examp...

Coercion-Resistant Internet Voting with Everlasting Privacy

The cryptographic voting protocol presented in this paper offers public verifiability, everlasting privacy, and coercion-resistance simultaneously. Voters are authenticated anonymously based on perfectly hiding commitments and zero-knowledge proofs. Their vote and participation secrecy is therefore protected independently of computational intractability assumptions or trusted authorities. Coerc...
