Abstract

This paper begins by describing Benaloh and Tuinstra's protocol for receipt-free elections, and then shows how this protocol, although correct, makes unrealistic assumptions and is impractical to implement. We then show how to modify this protocol to make it very practical to implement, by adding an additional "uncoercible" party to the protocol.
