摘要：In recent years, several electronic voting (e-voting) schemes for communication networks have been proposed. In 2006, Chang and Lee presented an anonymous electronic voting scheme which can be applied in real-world elections. However, this paper shows that Chang- Lee’s e-voting scheme suffers from susceptibility to security attacks. As a result, some essential security requirements of their e-voting scheme may be compromised. An improved scheme is suggested to enhance the security of their scheme.
