In order to satisfy dynamic authorization in service-oriented grid environment, a context and trust-based grid service authorization model (CTGSA) is proposed. First, model is defined formally. Benefiting from the mapping relation of user-role, role-service and service-resource assignment, model can provide authorization using service-oriented method, which reduces the management overhead greatly. Context and trust are incorporated into authorization. The privilege to subject is granted dynamically based on context and trust information collected from the system environment. Security, flexibility and scalability of the model are analyzed in the end.
