1. A tally-hiding voting system, in which the tally that is released consists of only the winner without the vote count. Our proposal builds on a novel solution to the millionaire problem which is of independent interest.
2. A self-tallying vote, in which the tally can be calculated by any observer as soon as the last vote has been cast --- but before this happens, no information about the tally is leaked.
3. Authentication of voting credentials, which is a new approach for electronic voting systems based on anonymous credentials. In this approach, the vote authenticates the credential so that it cannot afterwards be used for any other purpose but to cast that vote. We propose a practical voting system that instantiates this high-level concept.Category / Keywords: cryptographic protocols / electronic voting Original Publication (with minor differences): USENIX Journal of Election Technology and Systems Workshop 2015 Date: received 13 Aug 2015 Contact author: alan szepieniec at esat kuleuven be Available format(s): PDF | BibTeX Citation Version: 20150814:154636 (All versions of this report) Short URL: ia.cr/2015/809 Discussion forum: Show discussion | Start new discussion
