Defeating Malicious Servers in a Blind Signatures Based Voting System

In this paper, we present two failures in the blind signatures based voting system Votopia [2] which has been tested during the last World Soccer Cup. We then propose a fix which relies on fair blind signatures. The resulting scheme is practical, satisfies the fundamental needs of security in electronic voting, including public verifiability, and compares favorably with other like systems in terms of computational cost. As an illustration, our variant of Votopia has been successfully trialed during the French referendum on the European Constitution in May 2005.
