Mu and Varadharajan proposed a remote voting paradigm in which participants receive a blindly signed voting credential that permits them to cast a vote anonymously. If some participant tries to cheat by submitting more than one vote, her anonymity will be lifted. In the last years, several proposals following this paradigm, including Mu and Varadharajan's, have been shown to be cryptographically weak. In this paper we first show that a recent proposal by Baseri et al. is also weak. After that, we give a general construction that, employing an offline e-coin protocol as a building block, provides an anonymous voting system following the aforementioned paradigm. © 2014 Elsevier Ltd.
