Basic knowledge in cryptography might be helpful. Yet, this is not required.


Decision finding processes in most democratic societies are guided by the election of representatives. Some smaller states also conduct voting for particular decisions. Apart from political elections, a lot of other voting processes are in use to determine leaderships, opinions, ... Nowadays we require democratic elections to be free and fair. This implies several features, like anonymity and secrecy. (Secret elections only take place since about the middle of the nineteenth century.) German law requires even more:

Die Abgeordneten des Deutschen Bundestages werden in allgemeiner, unmittelbarer, freier, gleicher und geheimer Wahl gewählt. GG Art. 38 Abs. 1 Satz 1 (The members of the German Federal Diet are elected in general, direct, free, fair and secret elections.)

Since the advent of computers and the Internet people have tried to use the new means also in election processes. Major forces driving that are the cost and the election turnout. However, cheaper and faster election processes might have even more, yet unpredictable effects on society and democracy. The topic of the course shall be the treatment of the methods and the one or other solution for electronic elections. This ranges from simple voting machines to complete remote Internet election systems. In the latter, modern cryptographic methods are essential for ensuring major properties.
