Abstract

See full text

A public wireless access point network includes authorized access points sharing the same SSID and connected to a network core which implements centralized authentication so that wireless client devices can roam between authorized access points. Each authorized access point is adapted to detect the presence of unauthorized rogue access points posing as authorized access points. The authorized access points inspect data packets received from wireless client devices which have roamed into range and from the addressing information in the MAC layer and IP layer can determine whether the wireless device has previously connected to a rogue access point. If such a determination is made, the user of the device is alerted that their confidential information may have been compromised.
