Coercion-Resistant Internet Voting in Practice
Internet voting continues to raise interest both among research and society. Throughout the last decades, many Internet voting schemes have been developed, each one providing particular properties such as receipt-freeness or end-to-end verifiability. One attractive scheme is the JCJ / Civitas scheme due to its property of making coercion attacks ineffective. Neumann and Volkamer [NV12] analyzed the scheme and identified significant usability issues. To overcome these drawbacks, the authors extended the original work by integrating smart cards. In a follow-up work, Neumann et al. [NFVK13] conducted a theoretical performance analysis for this extension and improved the extension towards its applicability in real-world elections. Their analysis left several real-world considerations open for future work. The present work addresses these gaps: We present a prototype implementation of the revised extension and assess its real-world performance. Based on this contribution, we are able to conclude that the revised extension is feasible to be used in real-world elections.
