Ensuring secure interoperation in multidomain environments based on role based access control (RBAC) has drawn considerable research works in the past. However, RBAC primarily consider static authorization decisions based on subjects' permissions on target objects, and there is no further enforcement during the access. Recently proposed usage control (UCON) can address these requirements of access policy representation for temporal and time-consuming problems. In this paper, we propose a framework to facilitate the establishment of secure interoperability in multidomain environments employing Usage Control (UCON) policies. In particular, we propose an attribute mapping technique to establish secure context in multidomain environments. A key challenge in the establishment of secure interoperability is to guarantee security of individual domains in presence of interoperation. We study how conflicts arise and show that it is efficient to resolve the security violations of cyclic inheritance and separation of duty. © 2009 Springer Berlin Heidelberg.
