TrustFraMM: Meta Description for Trust Frameworks

Due to the boom in trust research new Trust Frameworks are created within short time intervals providing specific solutions for different domains. But these frameworks miss a common understanding and shared description. Based on available categorizations and surveys we collected key components already identified within Trust Management and created a generally applicable meta-model, which aims at creating the common ground for future trust research in computer science. This model consists of well-defined elements, procedures and relations. By applying our model to existing frameworks we show that it is sound. This process also led to the identification of common implementations of our meta-model elements and to the definition of their interfaces. These elements will be able to support future research and system design.
