Over the past years, many different approaches and concepts in order to increase computer security have been presented. One of the most promising of these concepts is Trusted Computing which offers various services and functionalities like reporting and verifying the integrity and the configuration of a platform (attestation). The idea of reporting a platform’s state and configuration to a challenger opens new and innovative ways of establishing trust relationships between entities. However, common applications are not aware of Trusted Computing facilities and are therefore not able to utilise Trusted Computing services at the moment. Hence, this article proposes an architecture that enables arbitrary applications to perform remote platform attestation, allowing them to establish trust based on their current configuration. The architecture’s components discussed in this article are also essential parts of the OpenTC proof-of-concept prototype. It demonstrates applications and techniques of the Trusted Computing Group’s proposed attestation mechanism in the area of personal electronic transactions.
