Interoperable Role-Based Access Control (IRBAC) 2000 model can be used to accomplish security interoperation between two or more administrative domains via role association and dynamic role translation. However, Static Separation of Duties (SSoD) is not considered in the IRBAC 2000 model, so the problem of inter-domain static mutual exclusive roles constraints violation can arise. This paper proposes a novel method based on colored Petri nets to model and analyze IRBAC 2000 model so as to detect Static Mutual Exclusive Roles (SMER) constraints violation.
