摘要：Mobile technologies made their headway by offering more flexibility to end-users and improve the productivities. Many businesses have quickly adopted them so as to gain and sustain a competitive edge, especially in global roaming. Within the application of ubiquitous access and pervasive communication, security, privacy and QoS becomes a critical issue during global mobility, particularly in getting smooth and seamless mobile services by decreasing handover latency. Based on single sign on and the context transfer protocol, this paper proposes a dynamic fast authentication and authorization scenario during inter-domain mobility, that can save one trip communication time consummation between administrative domains.
