摘要：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.
