Abstract

In 1998, Mu and Varadharajan proposed an anonymous secure e voting scheme over a network. Unfortunately, many researches have pointed out that Mu and Varadharajan’s scheme was not secure. Attackers can easily forge a valid ballot and can vote more than once. Later, Lin et al. proposed a scheme that improved upon Mu’s scheme. Lin et al. claimed that their scheme cannot only prevent double voting but can also defend against attacks from conspiring parties. In this study, we shall show that Lin et al. scheme still cannot prevent double voting and cannot detect forged ballots. A voter can vote more than once without being detected. Moreover, an attacker can forge valid tickets and pass the verification of authentication server.
