A Representation Model of Trust Relationships with Delegation Extensions

Abstract. Logic languages establish a formal framework to solve authorization and delegation conﬂicts. However, we consider that a visual representation is necessary since graphs are more expressive and understandable than logic languages. In this paper, and after overviewing previous works using logic languages, we present a proposal for graph representation of authorization and delegation statements. Our proposal is based on Varadharajan et al. solution, though improve several elements of that work. We also discuss about the possible implementation of our proposal using attribute certiﬁcates.
