Abstract

In open and distributed property-based access control systems, access rights are granted because of presented certified properties. However, controlling agents base their access decisions not only on presented certified properties. Crucial factors are the correlations between certified properties, experiences and expectations concerning other participating agents, and the resulting trust modalities. This work identifies the essential correlations and demonstrates how they can be explicitly integrated in access decisions.
