SECURE ROAMING AUTHENTICATION MECHANISM FOR WI-FI BASED NETWORKS

摘要

A severe contest for seamless roaming between inter-domain Wireless Fidelity technologies is to build a trust model in a milieu of several WLAN service providerswith varying charging or billing options and authentication mechanisms. This study implements a comprehensive single sign-on prototype for the unification of various WLANservice providers. Users choose the suitable single sign-on verification scheme from theauthentication abilities existing on the WLAN service providers that prevent the exposure of their information from illegitimate users while roaming. A composite layer 2 andweb-based authentication method intended to ensure secure transmission of cryptographickeys while maintaining the prevailing WLAN charging options. The study deployed RADIUS and liberty based protocols to control unauthorized access to the WLAN networkresources. In this paper, RADIUS simulation performed shows how authentication, authorization and accounting standards can be used to allow only the legitimate client toaccess the network while averting unauthorized users. In addition, the performance ofthe confederated Wi-Fi networks was shown by performing an experiment for the negotiation based authentication protocol with policy engine and authentication framework viathe web-based protocol. "The proposed mechanism Tevealed low latencies results which aresuitable to support seamless user experience.
