For many years now, cryptography has been keeping messages secure for senders, irrespective of the routing to the destination. This same technology can be used to keep votes secure for voters, from the casting of the vote all the way through to the inclusion of the vote in the final tally. This state-of-the-art survey addresses the challenges faced in establishing a trustworthy electronic voting system. The 24 contributions included in the volume were carefully reviewed and selected from the presentations given during a series of workshops on trustworthy elections held over the last decade. Topics addresses range from foundational and theoretical aspects to algorithms and systems issues, as well as applications in various fields.

This state-of-the-art survey examines the challenges to establishing a trustworthy electronic voting system. Coverage ranges from foundational and theoretical aspects of cryptography, to algorithms and systems, to real-world applications of technology.
