Establishing interoperability is the first and foremost problem of secure interoperation in multi-domain environments. In this paper, we propose a framework to facilitate the establishment of secure interoperability in decentralized multi-domain environments, which employ Role-Based Access Control (RBAC) policies. In particular, we propose a method for setting up interoperating relationships between domains by combining role mappings and assignments of permissions to foreign roles. A key challenge in the establishment of secure interoperability is to guarantee security of individual domains in presence of interoperation. We present rules which regulate the interoperability. These rules ensure that constraints of RBAC policies are respected when cross-domain accesses are allowed.
