Cryptanalysis and Security Enhancement on the Generation of Mu-Varadharajan Electronic Voting Protocol
Mu and Varadharajan proposed an electronic voting scheme and claimed that their scheme authenticates the Voters, protects the anonymity of them, and detects the identity of double voters. Due to some weaknesses in Mu-Varadharajan scheme, several modified schemes have been proposed by Lin et al., Hwang et al., Rodr?guez-Henr?quez et al. and Asaar et al.; however this paper shows that these schemes suffer from some weaknesses in fulfilling the pointed properties. For this purpose, the authors get Hwang et al. scheme as a case study and apply the new attacks on it. Also they consider the applicability of the attacks on other pointed schemes.
