Recently, Mu and Varadharajan proposed an efficient electronic-voting schemes. They claimed to protect voter's anonymity, to detect double voting, and to authenticate the voters. In this article, we will show the failures of the claimed functions: (1) the authority can easily identify the owner of a cast ballot; (2) a valid voter or any one can vote more than once without being detected; (3) any one can forge ballot without being authenticated. In addition to the failures of the claimed functions, we also point out other weaknesses in Mu-Varadharajan's scheme.
