Large-scale distributed systems that are provided in an inter-organizational manner require scalable, dynamic access control paradigms for dealing with known, but also with new users. This paper presents an innovative, trust management based approach for such scenarios. It aggregates and evaluates trust levels from several trust dimensions and has been implemented as a trust based access control (TBAC) framework using several standard components.
