User Experience Design for E-Voting: How mental models align with security mechanisms
This addresses usability and security challenges for e-voting users, but it is incremental as it builds on existing protocols and prior analysis.
The paper tackled the problem of aligning user mental models with security mechanisms in e-voting by developing a mobile app based on the Selene protocol and testing it with 38 participants, resulting in proposed design improvements for future protocols.
This paper presents a mobile application for vote-casting and vote-verification based on the Selene e-voting protocol and explains how it was developed and implemented using the User Experience Design process. The resulting interface was tested with 38 participants, and user experience data was collected via questionnaires and semi-structured interviews on user experience and perceived security. Results concerning the impact of displaying security mechanisms on UX were presented in a complementary paper. Here we expand on this analysis by studying the mental models revealed during the interviews and compare them with theoretical security notions. Finally, we propose a list of improvements for designs of future voting protocols.
