Abstract
In this paper a Timed Automata (TA) based verification framework is proposed for Temporal RBAC. Roles, users, permissions - three basic components of RBAC are modeled using TA. These components interact with each other through channel synchronization. A parallel composition of TA is used to construct the complete system. Temporal constraints on roles, user-role assignments and role-permission assignments are conveniently expressed in this representation. Furthermore, both role hierarchy and separation of duty (SoD) have been incorporated in the proposed framework. Security properties are specified using Computation Tree Logic (CTL) and verified by model checking. © 2008 Springer Berlin Heidelberg.
