WPA/WPA2 Authentication
When a host wanting WLAN access needs to be authenticated in a network
using WPA or WPA2, the following steps occur:
Step 1. An 802.1x/EAP supplicant on the host contacts the AP (or
WLAN controller, if it is a lightweight AP) using 802.1x.
Step 2. The AP or WLAN controller uses RADIUS to contact the AAA
server, and attempts to authentication the user.
Step 3. If the authentication succeeds, all traffic from the client to the AP
is encrypted.
