Inter-Domain Authentication for Seamless Roaming in Heterogeneous Wireless Networks.
Master's Thesis, University of Pittsburgh.

Abstract
The convergence of diverse but complementary wireless access technologies and inter-operation among administrative domains have been envisioned as crucial for the next generation wireless networks that will provide support for end-user devices to seamlessly roam across domain boundaries. The integration of existing and emerging heterogeneous wireless networks to provide such seamless roaming requires the design of a handover scheme that provides uninterrupted service continuity while facilitating the establishment of authenticity of the entities involved. The existing protocols for supporting re-authentication of a mobile node during a handover across administrative domains typically involve several round trips to the home domain, and hence introduce long latencies. Furthermore, the existing methods for negotiating roaming agreements to establish inter-domain trust rely on a lengthy manual process, thus, impeding seamless roaming across multiple domains in a truly heterogeneous wireless network. In this thesis, we present a new proof-token based authentication protocol that supports quick re-authentication of a mobile node as it moves to a new foreign domain without involving communication with the home domain. The proposed proof-token based protocol can also support establishment of spontaneous roaming agreements between a pair of domains that do not already have a direct roaming agreement, thus allowing flexible business models to be supported. We describe details of the new authentication architecture, the proposed protocol, which is based on EAP-TLS and compare the proposed protocol with existing protocols.
