| Abstract: | An electronic voting system makes it possible for the voters to cast their ballots over the computer network. Hence, voters can participate in elections without having to go to the polling places, which is more convenient and efficient. To design a practical voting scheme, Mu and Varadharajan have recently proposed an anonymous secure electronic voting scheme to be applied over the network. It does not only protect voters' privacy and prevent double voting, but also suits large-scale elections. However, the scheme has a weakness in security; that is, some voters may still double vote without being detected and may even reveal information they should not. In this paper, we shall show this weakness and improve the scheme to increase the protection against fraudulence. |
