Abstract: A fundamental security problem in collaborative environments (CEs) is to control the admission of users to collaborations typically based on their job duty or skills. Current authorisation solutions for CEs focus on centralised policy management and are based on privilege credentials. In this paper, we propose a formal model that rigorously and unambiguously captures an innovative role structure, not solely dependent on naming methods, that takes into account organisational as well as functional characteristics to provide a practical role-assignment methodology between organisations in CEs. The applicability of our approach is investigated through a realistic case study.
