Determine the Resilience of Evaluated Internet Voting Systems

Internet voting gets more and more popular. It is generally accepted that an Internet voting system needs to be evaluated. The existing evaluation frameworks try to be as system-independent as possible. Because of that distributed trust concepts like separation of duty for the voting servers, four eyes principle for administrators and the election commission, as well as the multiplicity of control functions like for the counting of votes cannot be demanded precisely. This article proposes to extend the evaluation of Internet voting systems by the computation of a so called k-resilience value. This value defines the robustness of a system and helps to identify vulnerabilities. Besides the introduction and discussion of this value, it is computed for existing Internet voting systems.
