RIES: Internet voting in action

RIES stands for Rijnland Internet Election System. It is an online voting system that has been used twice in the fall of 2004 for in total over two million potential voters. In this paper we describe how this system works. Furthermore we describe how the system allowed us to independently verify the outcome of the elections - a key feature of RIES. To conclude the paper we evaluate possible threats to this system and describe some possible points for improvement
