Proposal for Swedish remote electronic voting system

By: Viktor Collin & Hampus Ohlsson

Abstract

Electronic voting is an extensive topic related to many difficult issues. It is hard to fulfil all desired characteristics and security requirements, which is demonstrated by the lack of systems in use today. More and more services are moving online to the digital sphere, but the general election in Sweden is still a manual and costly process. With the growing demand and popularity of online services today, an electronic voting system might be a necessity to maintain voter turnout in the future. In this report we investigate how to model a reliable and trustworthy remote electronic voting system for use in Sweden, so that a vote is submitted in the safest manner possible while maintaining confidentiality and verifiability through the entire chain. It is based on the “Scratch, Click & Vote” scheme published by Kutylowski and Zagórski (2010), but with some modifications to better suit the Swedish electoral system. The system is built upon distribution of knowledge and responsibility between two different parts, a Proxy and an Election Authority (EA). It aims to fulfil all security requirements desirable from a remote electronic voting system while protecting the secrecy and integrity of the ballot.
