Mechanisms for Security and Authentication of Wi-Fi Devices
This paper presents an overview of the different approaches for Wi-Fi device security with particular focus on public hotspots. This mainly involves solving the authentication problem. Common, as well as alternative solutions are presented and critically discussed with respect to the user's security and the usability. Today, public hotspots are not as secure as they could be if they implemented current standards and protocols for secure wireless networking. The issues with these new standards in public network environments are discussed and possible solutions presented. In order to facilitate this discussion, several concepts, protocols and standards in the context of wireless LAN security are presented. The paper concludes with an evaluation of the different approaches for hotspot authentication.
