Coercion-Resistant Cryptographic Voting

Remote electronic voting is a promising concept. Voters are enabled to cast their votes over the Internet, from arbitrary computers. It offers convenience and does not require geographical proximity on the election day. Thus, it has the potential to allure those groups of voters that regularly abstain from general elections. However, in order to implement free and secret electronic elections, the threats of vote buying and coercion against the voters need to be addressed.

In this research project, a cryptographic approach that deals with these issues is investigated. In particular, a cryptographic voting protocol is designed, evaluated and prototypically implemented that offers mechanisms to protect voters against coercion and thwarts vote buying. 

The research was carried out together with the Cryptography and Computeralgebra group at Technische Universität Darmstadt. The associated diploma thesis was finalist of CAST Award IT Security 2006.

In addition, it lead to a cooperation with the BMWi-funded project "voteremote". The results of the cooperation were nominated for the OCG e|Gov Innovationaward 2011.
