We modify the design of Belenios-Cai from the user perspective without changing its core cryptographic mechanism. The goal is to increase\u00a0its usability by letting the voter simply check whether two symbols\u00a0are equal or different.<\/jats:p><jats:p>We conducted a user-study among 165 participants in\u00a0a research center to evaluate\u00a0the usability of our implementation of Belenios-CaI. Since\u00a0the cast-as-intended mechanism assumes that voters make some random choices, we also evaluate whether the choices made by voters\u00a0are sufficiently \u201crandom\u201d to provide verifiability and whether it\u00a0could affect their privacy. The study shows that, for\u00a0our population, Belenios-CaI is considered as usable with the random choices of the voters seeming sufficient for verifiability and privacy.<\/jats:p>","DOI":"10.1007\/978-3-031-72244-8_1","type":"book-chapter","created":{"date-parts":[[2024,9,22]],"date-time":"2024-09-22T19:01:32Z","timestamp":1727031692000},"page":"1-19","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Belenios with\u00a0Cast-as-Intended: Towards a\u00a0Usable Interface"],"prefix":"10.1007","author":[{"given":"V\u00e9ronique","family":"Cortier","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierrick","family":"Gaudry","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anselme","family":"Goetschmann","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sophie","family":"Lemonnier","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,9,23]]},"reference":[{"unstructured":"Google Fonts: Material icons (2024). https:\/\/fonts.google.com\/icons","key":"1_CR1"},{"issue":"6","key":"1_CR2","doi-asserted-by":"publisher","first-page":"574","DOI":"10.1080\/10447310802205776","volume":"24","author":"A Bangor","year":"2008","unstructured":"Bangor, A., Kortum, P.T., Miller, J.T.: An empirical evaluation of the system usability scale.
