EVIV: An end-to-end verifiable Internet voting system

Traditionally, a country’s electoral system requires the voter to vote at a specific day and
place, which conflicts with the mobility usually seen in modern live styles. Thus, the
widespread of Internet (mobile) broadband access can be seen as an opportunity to deal
with this mobility problem, i.e. the adoption of an Internet voting system can make the live
of voter’s much more convenient; however, a widespread Internet voting systems adoption
relies on the ability to develop trustworthy systems, i.e. systems that are verifiable and
preserve the voter’s privacy. Building such a system is still an open research problem.
Our contribution is a new Internet voting system: EVIV, a highly sound End-to-end Verifiable
Internet Voting system, which offers full voter’s mobility and preserves the voter’s
privacy from the vote casting PC even if the voter votes from a public PC, such as a PC at
a cybercafe´ or at a public library. Additionally, EVIV has private vote verificationmechanisms,
in which the voter just has to perform a simple match of two small strings (4-5 alphanumeric
characters), that detect and protect against vote manipulations both at the insecure vote
client platform and at the election server side.
