Abstract
Several quantum protocols were proposed in a recent paper by Vaccaro, Spring and Chefles for ensuring the anonymous voting in a number of different scenarios. However, it is shown that their protocols are very vulnerable in terms of security. Improved schemes are also presented to recover the security.
