At the same time, the security concerns facing any distributed application are magnified when the task is so crucial to democratic society. In addition, some of the electoral process loses transparency when it is encapsulated in information technology. In this paper, we examine the public record of three recent elections that used Internet voting. Our specific goal is to identify any potential flaws that security experts would recognize, but may have not been identified in the rush to implement technology. To do this, we present a multiple exploratory case study, looking at elections conducted between 2006 and 2007 in Estonia, Netherlands, and Switzerland. These elections were selected as particularly interesting and accessible, and each presents its own technical and security challenges. The electoral environment, technical design and process for each election are described, including reconstruction of details which are implied but not specified within the source material. We found that all three elections warrant significant concern about voter security, verifiability, and transparency. Usability, our fourth area of focus, seems to have been well-addressed in these elections. While our analysis is based on public documents and previously published reports, and therefore lacking access to any confidential materials held by electoral officials, this comparative analysis provides interesting insight and consistent questions across all these cases. Effective review of Internet voting requires an aggressive stance towards identifying potential security and operational flaws, and we encourage the use of third party reviews with critical technology skills during design, programming, and voting to reduce the changes of failure or fraud that would undermine public confidence."}],"file":[{"relation":"main_file","content_type":"application/pdf","access_level":"open_access","file_id":"6316","file_name":"JOURNAL VERSION.pdf","file_size":1544790,"date_created":"2018-12-18T13:16:07Z","creator":"hsiemes","date_updated":"2018-12-18T13:16:07Z"}],"publication":"IEEE Transactions on Information Forensics \\& Security","keyword":["e-voting","Internet voting","Internet election","security","verifiability","RIES","Estonia","Neuch{\\^a}tel"],"ddc":["000"],"language":[{"iso":"eng"}],"year":"2009","issue":"4 Part","title":"Security in Large-Scale Internet Elections: A Retrospective Analysis of Elections in Estonia, The Netherlands, and Switzerland","publisher":"IEEE","date_created":"2018-11-14T14:06:44Z"},{"year":"2009","citation":{"chicago":"Schryen, Guido, and Rouven Kadura. “Open Source vs. Closed Source Software: Towards Measuring Security.” In <i>24th Annual ACM Symposium on Applied Computing</i>, 2009.","ieee":"G.

Thereby, it provides an extensive empirical analysis of vulnerabilities in terms of mean time between vulnerability disclosures, the development of disclosure over time, and the severity of vulnerabilities, and allows for validating models provided in the literature. The investigation reveals that (a) the mean time between vulnerability disclosures was lower for open source software in half of the cases, while the other cases show no differences, (b) in contrast to literature assumption, 14 out of 17 software packages showed a significant linear or piecewise linear correlation between time and the number of published vulnerabilities, and (c) regarding the severity of vulnerabilities, no significant differences were found between open source and closed source."}],"type":"conference","publication":"15th Americas Conference on Information Systems","extern":"1","language":[{"iso":"eng"}],"file_date_updated":"2018-12-18T13:16:39Z","ddc":["000"],"keyword":["Vulnerabilities","security","open source software","closed source software","empirical comparison"],"user_id":"61579","department":[{"_id":"277"}],"_id":"5647","citation":{"apa":"Schryen, G.
