Abstract: This article exploits the idea of using the role-based access control model for the mobile agent authorisation problem. In our approach, when an agent migrates to a specific platform, the host assigns it a role from the local role hierarchy. The assignment is based on role decomposition that every host is eligible to perform according to a set of well-established rules. We analyse the matching procedure and we demonstrate a role management system application which is capable to compare roles and thus to assign local roles to upcoming agent roles. Moreover, we present our first efforts to model mobile agent behaviour using Coloured Petri-Nets, a powerful modelling language for systems in which communication and resource distribution play a very important role.
