Voting with Unconditional Privacy by Merging Prêt-à-Voter and PunchScan

Jeroen van de Graaf

Abstract

We present a detailed comparison of the Prêt-à-Voter and Punchscan protocols for booth voting. We also describe a simpler variation that keeps the ballot layout of Prêt-à-Voter but borrows the cryptography from Punchscan, which is based on any commitment scheme. By using unconditionally hiding commitments we obtain a conceptually very simple voting protocol with unconditional privacy.

Note: This paper is the result of a long-overdue task I had set myself: going to the cryptographic core of both Pret-a-Voter and PunchScan. The first, four-page version was presented as a short paper to the Simposio Brasileiro de Seguranca.
