Abstract
Secure hotspot roaming in wireless networks. An enterprise works with one or more hotspot providers to provide secure access to its clients through hotspot locations. The enterprise provides the (hotspot) service provider (SP), with the addresses of enterprise controllers used for client authentication. The SP maintains a database which maps the enterprise realm to the address of the enterprise controller. When a client connects to a hotspot access point (AP), the hotspot AP sends client information such as MAC address to a SP controller. The SP controller determines if the client is new or already known. If the client is known and the realm associated with the client has an entry in the realm to enterprise database, the hotspot AP is instructed to begin client authentication with the specified enterprise controller. If the client is unknown, authentication begins with the SP controller, and the client is queried for realm information.
