In the past, researchers have proposed many voting schemes that satisfy a wide range of security properties. These schemes often rely on strong trust assumptions and do not consider the voter sufficiently, which currently renders them inappropriate for usage in real-world elections. In this paper we focus on the voting scheme Civitas, which features provably strong security properties, such as end-to-end verifiability and coercion-resistance. We identify the strong trust assumptions and usability weaknesses of the scheme, which currently prevent its usage in real-world elections. Based on these results, we show how most of these strong trust assumptions can be implemented, e. g., by using eID cards in order to overcome Civitas' most critical usability problem, namely credential handling. Together with a voter-process description and a user-interface, we pave the way for the use of Civitas in real-world elections.
