An Authentication and Authorization Protocol Using Ticket in Pervasive Environment

An AAA protocol is an information protection technology that systematically provides authentication, authorization and accounting functions not only in existing wired networks, but also in rapidly developing wireless networks. Currently, standardization of various applied services is in progress which involves AAA standardization for a mobile user in a wireless network. And, various studies have considered using AAA with a roaming service in a mobile IPv6 network, between heterogeneous networks. In this paper, we proposed an ID-based ticket for user authentication with a mobile device in a ubiquitous environment. There is seamless service, even when a mobile device moves from the home network to a foreign network. In addition, since a ticket renewed from the foreign network, the overhead of the home authentication server is reduced, and the anonymity ID provides a way to guarantee anonymity while using a service.
