Role-Based Access Control (RBAC) is a popular authorisation control scheme under which users are assigned to certain roles, and the roles are associated with permissions. This paper presents a novel mechanism for modelling workflow execution in cluster-based resource pools under Role-Based Access Control (RBAC) schemes. Our modelling approach uses Coloured Timed Petri-Nets, and various authorisation constraints are modelled, including role constraints, temporal constraints, cardinality constraints, Binding of Duty and Separation of Duty constraints, etc. The interactions between workflow authorisation and workflow execution are also captured in the model. In this paper, the modelling mechanism is developed in such a fashion that the construction of the authorisation model for a workflow can be automated.

A Petri-net simulation tool, the CPN-Tool, is utilised to implement the developed modelling mechanism and simulate the constructed model.
