| Abstract | <span style="font-family: Verdana, Arial, Helvetica, sans-serif; font-size: 12.8px; ">One of the main open issues in electronic government is the fact that the individual users' multi-purpose computing platforms are used. In terms of security, no guarantee is given since these platforms are not under the government authority's control. Even worse, the number of malware infected computing platforms increases. This so-called Secure Platform Problem and approaches aiming to solve it are objects of investigation in this work. We define criteria that need to be ensured to address this problem. Furthermore, we propose a taxonomy to classify existing approaches. Based on the classification and the criteria, we analyze the different types of approaches by providing concrete examples. Hereby, we show that none of the existing approaches fully meets our criteria. Thereby, we focus on the most security critical class of electronic government services, namely electronic voting over the Internet. However, most of the discussed approaches as well as the criteria and classification can also be applied to other governmental applications.</span> |
