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.
