Session 1: Chair Robert Krimmer
9:00-9:45 Democracy in the Digital Age
Carsten Schürmann, IT University of Copenhagen, Denmark
Abstract. In this talk, I will try to develop and propose a vision for the Marie Curie ITN proposal as a basis for discussion. Furthermore I will given an overview about how we structure the next days of the workshop. Slides.
9:45-10:30 e‐Voting & Law: What does E2E mean for legal
Jordi Barrat, Universitat Rovira i Virgili, Spain
Abstract. Once accepted that verifiability is a cornerstone in any e‐voting solution, several technical researches have been conducted in order to set up End‐to‐End (E2E) electronic voting platforms. The so‐called second generation of e‐voting mechanisms intends to adopt such new features. However, legal approaches still remain somehow aside. Specific legal frameworks for E2E mechanisms have already been developed, but normally they do not highlight potential shortcomings. They only intend to ease E2E implementation. They adapt the legal language to E2E scientific requirements, but it is worth wondering whether they manage to do exactly the opposite, that is to say, to generate specific legal pre‐conditions for E2E implementations.
In this regard, please note that law is focused on the content (what) as well as on the procedure (how), the subject (who), the cause (why) and the timeframe (when). While E2E procedures might provide sound technical evidence, that is to say, contents that fulfil what is expected by computer scientists, legal experts may require supplementary data on how and when such evidence have been generated, who were the responsible and which is the purpose.
Obviously E2E experts will have the appropriate answer for each doubt, but perhaps just in technical (and not in legal) terms. Evidence would have been generated in compliance with international scientific standards, but let us wonder whether such standards also apply for specific legal procedures. What is evidence for a computer scientist might not be evidence for a judge. Or at least the judge could weigh the same data in a different way. Taking into account all these premises, the presentation will explore how to adapt E2E voting platforms to legal pre‐conditions.
Session 2: Chair Bernhard Beckert
Robert Krimmer, Tallin University of Technology, Estonia
11:30-12:15 Formal Verification of e-Voting protocols: Models, Properties and Tools
Jannik Dreier, ETH Zurich, Switzerland
Abstract. Since the beginning of e-voting, cryptographic voting protocols have been analyzed using formal verification tools. In this talk I will present our work in the area, ranging from (human) models over various properties, verification techniques and tools, to applications to other domains. In the end I will briefly discuss ongoing work, and perspectives for the project proposal.
Session 3: Chair Aggelos Kiayias
13:00-13:45 Human Centered Security and Privacy by Design for Electronic Voting
Oksana Kulyk, University of Darmstadt, Germany
13:45-14:30 Program Verification
Bernhard Beckert, University of Karlsruhe, Germany
In this talk, I will give an overview of our work on specifying and verifying properties of voting systems. We have used various deductive methods to prove declarative properties, such as monotonicity, for simple plurality voting or more complex systems, such as single transferable vote. At the beginning of my talk I will give a brief introduction into specification and deductive verification for non-experts. Slides.

Session 4: Chair Filip Zagorski
14:45-15:30 The Demos E-voting system
Aggelos Kiayias, National and Kapodistrian University of Athens, Greece
Abstract. In this talk we describe the demos e-voting system (www.demos-voting.org) including a description of the design choices behind the system architecture, its novel cryptographic algorithms as well as various issues related to its deployment in voting procedures. Demos is an online e-voting system that supports end-to-end verifiability, i.e., it allows voters to obtain a form of receipt after ballot-casting that enables the verification of the inclusion of their vote into the final tally while preserving the privacy of their choice. Demos utilizes novel cryptographic methods to ensure end-to-end verifiability without the need for ideal randomness as previous systems.The system is suitable for both onsite as well as online voting.
15:30-16:15 EMB perspective on the use of New voting technology (NVT) in Norway
Henrik Nore, Norway
In 2010 the ministry (EMB) in Norway started a process of renewing the ICT platform used for elections. This had been the responsibility of the municipalities. They are by law responsible for conducing the election The government decided that the ministry should acquire, implement, operate and maintain a ICT system to be used for all elections in Norway. This should include internet voting, ballot scanning and a fully distributed electronic electoral roll to all poll stations. The solution should be based on open source. I will tell the reason why Norway decided to do this and what happened. Slides.
Session 5: Chair Jordi Barrat
Judith Simon, IT University of Copenhagen, Denmark
17:15-18:00 Rump Session
Filip Zagorski, Worclaw University, Poland
Workshop dinner: Madklubben, Store Kongensgade 66, 19:00.
