The Design of Efficient Internetwork Authentication for Ubiquitous Wireless Communications

Overview

The security problem is one of the major challenges in internetworking. To date, most research on internetwork authentication has focused on centralized authentication approaches, where the home network participates in each authentication process. For high latency between the home and visiting networks, such approaches tend to be inefficient. This paper describes chained authentication, which requires collaboration between adjacent networks without involvement of the home network. After categorizing chained protocols, the paper proposes a novel design of chained authentication methods under 3G-WLAN internetworking.
