Coercion-resistant hybrid voting systems
(4th International Conference on Electronic Voting 2010, 2010) Spycher, Oliver; Haenni, Rolf; Dubuis, Eric
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 based on this feature. Our solution may be of interest to governments, which aim at integrating paper-based and electronic voting systems rather than replacing the former by the latter.

Why public registration boards are required in E-voting systems based on threshold blind signature protocols
(4th International Conference on Electronic Voting 2010, 2010) Koenig, Reto E.; Dubuis, Eric; Haenni, Rolf
In this paper, we demonstrate that e-voting protocols based on threshold blind signatures from multiple authorities allow a coalition of eligible voters to cast more than votes. This property presents a serious violation of the principles of democracy in the voting process. We analyze the applicability of this violation and provide a generic solution using a public registration board and modified threshold signature schemes.
