Abstract: Lin, Hwang and Chang (2003) have proposed an electronic-voting scheme which can be utilised in large-scale elections, and claimed that it detects double voting. In this article, by presenting an attack, we show that voters can successfully vote more than once without being detected. Then, we propose a new modified scheme based on the Lin, Hwang and Chang|s (2003) scheme with the same efficiency to solve this weakness and analyse its security.

Keywords: double voting; electronic voting; e-voting; ticket unforgeability; voter anonymity; electronic democracy; e-democracy; voting fraud; electronic security.
