I&s Improved Anonymous Secure E-voting over a Network

In a democratic country voting is one of the most important activities. However, many eligible voters do not exercise their right simply because they do not want to visit a public booth where they can vote. In 1981, David Chaum first introduced the concept of electronic voting and attempted to overcome the problems associated with the traditional voting environment. Hereafter, Mu and Varadharajan proposed in 1998 an anonymous secure e-voting scheme over a network. They claimed that the proposed scheme is not only capable of preventing double voting but it can also protect the privacy of voters. However, many researchers afterwards have discovered that Mu and Varadharajan’s scheme is not secure. Attackers can easily forge a valid ballot and can vote more than once. In this paper, an e-voting scheme based on Mu and Varadharajan’s scheme is proposed that meets the following e-voting requirements: democracy, accuracy, anonymity, mobility and efficiency.
