Abstract
The diversity of the kinds of interactions between principals in distributed computing systems, including critical infrastructures, has expanded rapidly in recent years. However, such applications and their users are vulnerable with respect to both the diversity of the principals providing these services or data and the interactions between them. This paper introduces formalisms for a new trust model that addresses these limitations. The novelty of the new model is its ability to specify and reason about trust dynamically and when composed beyond pairwise relationships for a specific interaction. An intuitive and practical way is presented to manage end-to-end trust assessment for a particular activity, where multiple trust relationships are examined in order to derive the overall trust for the activity.
