    German Social Elections in 2023
    (E-Vote-ID 2023, 2023) Hilt, Tobias; Kulyk, Oksana; Volkamer, Melanie
    In 2023, the third largest election in German, the social elections (in German Sozialwahlen), offered an online channel for the first time. Of particular interest is the fact that the system provides a form of cast-as-intended verifiability, allowing the voter to verify that their vote was cast as intended and not manipulated by the device they used to cast their vote. This paper describes a first analysis of the overall voter experience with a special focus on this verifiability functionality. We utilize a cognitive walkthrough method, with three people having different levels of expertise regarding online voting, including a layman, a security expert, and a voting expert. Our findings reveal a number of issues with the system in terms of communication and presented information, and highlight areas in need of improvement to enhance user experience in particular with respect to the verifiability functionality.

    Voter Perception of Cast-as-Intended Verifiability
    (E-Vote-ID 2023, 2023) Hilt, Tobias; Sein, Kati; Mällo, Tanel; Willemson, Jan; Volkamer, Melanie
    The internet voting protocol deployed at Estonian political elections was enhanced by cast-as-intended vote verifyability mechanism in 2013 to reveal manipulations of the vote casting device by using a second device (most likely a mobile device as it needs to be euqipped with a camera). This paper studies voters' perception and comprehension of this mobile-device-based cast-as-intended verifiability mechanism. We conducted semi-structured interviews with 13 eligible voters who have cast an electronic vote at least once since the availability of this mechanism. While most participants were in favor of having the option to verify available, most were not aware of the main purpose to verify. Instead, they, for instance, thought it was designed to check that they had not made a mistake while selecting a candidate or to verify one's vote was tallied as intended. Thus, our findings highlight the need for improved communication on cast-as-intended verifiability in order to enable informed decisions whether to verify or not.
