Readiness of various eVoting systems for complex elections.
[Report]

Abstract

Electronic voting, or eVoting, systems in polling stations are becoming more and more widely implemented. However, they face several challenges when dealing with legally binding election systems. The purpose of this paper is to analyse the readiness of various eVoting systems for possible implementation in a highly complex election. As a representative for a complex election we look at the local election in Germany, because this one allows cumulative voting, vote splitting, crossing out of candidates, as well as vote casting for parties and candidates. We deduce how various systems perform and analyse them with respect to these requirements, and also against equally important criteria; usability, privacy and verifi- ability. The eVoting systems we evaluate in this paper reflect the wide variety of technologies currently available. They are; electronic tallying tools, scan based systems, DREs with VVPATs, and two cryptographic eVoting systems, Pretˆ a Voter and Scantegrity II. As a result ` we found out that none of these systems fully meet the criteria and, for the purpose of possible implementation for the local election in Germany, need to be improved. Based on this we provide some suggestions for improvements and recommendations for future work.
