Remote electronic voting or informally called "Internet-Voting" has been subject to research for several decades and is regularly part of the public debate. A special focus is thereby on remote voting procedures in uncontrolled environments. That is, election procedures which voters can use to cast their ballot conveniently from their own computer at home. Obviously, special security requirements are put on this kind of election procedures. This paper aims to present the legal requirements of general elections demanded by the example of the German constituion and derive appropriate cryptographical, technical, and organizational properties. Based on these, a methodology to assess remote electronic voting procedures regarding specific threat models is further developed. After having presented a broad survey of productively used as well as mostly academic voting procedures, those are evaluated and comparatively presented using the formerly developed methodology. Being the prototype of elections in uncontrolled environments, the postal voting procedure currently used in Germany is also assessed in order to embed the results into the overall discussion.
