    Faster coercion-resistant e-voting by encrypted sorting
    (E-Vote-ID 2023, 2023) Aranha, Diego F.; Battagliola, Michele; Roy, Lawrence
    Coercion resistance is one of the most challenging security properties to achieve when designing an e-voting protocol. The JCJ voting scheme, proposed in 2005 by Juels, Catalano and Jakobsson, is one of the first voting systems where coercion-resistance was rigorously defined and achieved, making JCJ the benchmark for coercion-resistant protocols. Recently, the coercion-resistance definition proposed in JCJ has been disputed and improved by Cortier, Gaudry, and Yang. They identified a major problem, related to leakage of the number of discarded votes by revoting; and proposed CHide, a new protocol that solves the issue and satisfies a stronger security notion. In this work we present an improved version of CHide, with complexity O(n log(n)) instead of O(n^2) in the number n of received ballots, that relies on sorting encrypted ballots to make the tallying phase faster. The asymptotic complexity of our protocol is competitive with other state-of-the-art coercion-resistant voting protocols satisfying the stronger notion for coercion resistance.

    French 2022 legislatives elections
    (E-Vote-ID 2023, 2023) Cortier, Véronique; Gaudry, Pierrick; Glondu, Stéphane; Ruhault, Sylvain
    For the 2022 legislative elections, France made use of Internet voting for a fraction of its voters, namely French voters from abroad. For the first time, France introduced the notion of verifiability and third party. We report here the role of the third party, its interaction with the ANSSI, what it meant in terms of verifiability, as well as its limitations.

    Swiss Online Voting Redesigned
    (E-Vote-ID 2023, 2023) Spycher, Oliver
    Switzerland is one of the few countries with a strong record in online voting in national elections and votes. After 15 years during which parts of the electorate cast their vote online, the trials were brought to a halt in 2019. This short-paper summarizes the developments in Swiss online voting since 2019, when the trial framework was redesigned, allowing trials to take place again in 2023. This article is a non-scientific contribution aimed at providing the e-voting community with essential background information on Swiss online voting. Thereby it sets a focus on the new role of academia in the trial phase.
