Yet another improvement over the Mu–Varadharajan e-voting protocol

In this paper we present a fully functional RSA/DSA-based e-voting protocol for online elections that corrects and improves a scheme previously proposed by Lin- Hwang-Chang [I. Lin, M. Hwang, C. Chang, Security enhancement for anonymous secure e-voting over a network, Comput. Stand. Interfaces 25 (2) (2003) 131–139.]. We found that Lin-Hwang-Chang's scheme and a recent modification of it by Hwang-Wen-Hwang [S. Hwang, H. Wen, T. Hwang, On the security enhancement for anonymous secure e-voting over computer network, Comput. Stand. Interfaces 27 (2) (2005) 163–168.] have an important weakness. Moreover, the scheme proposed by Yang-Lin-Yang [C. Yang, C. Lin, H. Yang, Improved anonymous secure e-voting over a network, Information and Security 15 (2) (2004) 185–191.] also suffers from this same problem. We describe in detail our findings and propose a new scheme to overcome the weakness we found in these schemes effectively. Finally, we describe the implementation details of our protocol and present its preliminary performance evaluation.
