Context-aware Trust Evaluation Functions for Dynamic Reconfigurable Systems

We acknowledge the fact that situational details can have impact on the trust that a Trustor assigns to some Trustee. Motivated by that, we discuss and formalize functions for determining context-aware trust. A system implementing such functions takes into account the Trustee’s profile realized by what we call quality attributes. Furthermore, the system is aware of some context attributes characterizing additional aspects of the Trustee, of the Trustor, and of the environment around them. These attributes can also have impact on trustor’s trust formation process. The trust functions are concretized with running examples throughout the paper.
