Özet:

Some of the countries use classical methods for elections. In such voting systems, people are forced to be in a predefined place and have to cast their votes in a limited time interval. Parallel to economic growth, priority of time on people’s life increased and such kind of limitations decreases the number of people who cast their vote. In order to make people’s lives easier, we need to add usable automated systems to elections such as Internet Voting (i-voting) systems. However, constructing an i-voting system needs comprehensive knowledge of various sciences like information technology and cryptography. Electronic voting is in general very sensitive in the sense that if any problem occurs in the designed system, then the society will have a question mark in their mind and this will diminish the percentage of people who use voting systems. In this thesis, many cryptographic protocols and i-voting systems are studied. Norway and Estonia are the countries who use i-voting solutions successfully for some years. We focused on their solutions and studied on a modified version of the Norwegian system.
