### Paper: Merging Pret-a-Voter and PunchScan

Authors: Jeroen van de Graaf URL: http://eprint.iacr.org/2007/269 Search ePrint Search Google We describe a variation of the Pret-a-Voter voting protocol that keeps the same ballot layout but borrows and slightly modifies the underlying cryptographic primitives from Punchscan, which is based on bit commitments. By using unconditionally hiding bit commitments, our protocol obtains unconditional privacy. We suggest a way to make cheating on the computational binding bit commitments impossible under assumptions that seem plausible for large-scale elections. Also we show ways to have several races on the Pret-a-Voter ballot, showing that with respect to ballot layout the protocols are almost identical.
