Voter anonymity and voting correctness are important issues for electronic voting
mechanisms. Compared electronic voting with traditional 1elections, an electronic voter is
able to cast his/her ballot through the Internet in any place and at any time if he/she can
access the network. Therefore, convenience and mobility make electronic voting become more
and more popular and electronic voting can be adopted in the real world with higher
feasibility. Recently, Chang and Lee presented an electronic voting (e-voting) scheme based
on the blind signature and the Diffie-Hellman key exchange methods for ensuring voter
anonymity and performance efficiency. They claimed that numerous essential requirements of
general electronic voting can be ensured in their e-voting scheme. Unfortunately, we found
that Chang-Lee’s e-voting scheme suffers from susceptibility to security attacks and some
critical security requirements of their e-voting scheme may be compromised. To prevent
security weaknesses of Chang-Lee’s e-voting scheme, in this paper, an improved version on
their e-voting scheme is proposed that not only keeps the merits of Chang-Lee’s e-voting
scheme but also enhances the security of their e-voting scheme.
