Abstract
"Baloti" is an online platform aiming at familiarizing foreign residents of Switzerland with their new political environment. The project is funded by the integration fund of the Swiss Confederation and carried out by an interdisciplinary team at the Zentrum für Demokatie in Aarau. As of September 2010, the platform will offer users to cast their electronic vote in the event of federal referendums. The ballot is meant to reflect the political opinion of foreign residents in a consultative manner.
The Baloti platform integrates "Selectio Helvetica" as its E-voting system which was developed by the E-voting group of the Bern University of Applied Sciences. It results from the “Swiss Vote” project funded by the Hasler Foundation.
We will present an outline of the E-voting protocol used in "Selectio Helvetica" and relate it to the security requirements that are specific to the domain of E-voting. Properties include individual and universal verifiability/auditability, secrecy of the ballot, proper authorization of votes and coercion-resistance. Further, we will describe how the implementation of “Selectio Helvetica” addresses the needs and restrictions given by the context of the Baloti project.
