The OSGi provides a service platform which ensures the interoperability between heterogeneous technologies and various devices in home network environment. Nowadays, user access control is one of the core parts which should be cleared, but there are no concrete researches yet. So in this paper, we propose a supplemented authorization policy management framework based on RBAC (Role-Based Access Control) for user access control at home network environment in which the OSGi service platform is operated. The proposed access control framework improves effectiveness, assures privacy and provides convenience at the same time. In conclusion, we provide the base to implement the effective, safe, and convenient the OSGi service platform by proposing the new framework in authorization and user administration part.
