A Taxonomy Refining the Security Requirements for Electronic Voting: Analyzing Helios as a Proof of Concept

Over the past years an approved set of security requirements for electronic voting has been established. However, there is no consistent perception of the exact content and scope of these requirements. Therefore, the corner stone for a comprehensive taxonomy refining the security requirements for electronic voting was laid in. In order to verify the validity of this taxonomy, we apply it to the voting schemes Helios 1.0 and 2.0. We provide amendments to the original taxonomy and demonstrate that it successfully distinguishes between different, but related voting schemes, thus supporting its relevance for the study of electronic voting systems.
