Access Control and Authentication for Converged Wireless Networks

This paper presents a novel AAA architecture featuring the use of role-based access control and authentication for a converged wireless network where a single operator, as in one of the North American operators who offer both cellular and DSL service, provides the converged services and broadband access. Important features, such as mutual authentication, fast roaming and NAT traversal issues in heterogeneous wireless networks, are discussed. In addition, the paper proposes a modeling approach to address converged network security in a systematic and cost efficient manner
