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.
