7.10.8.3  How WPS Works
When two WPS-enabled devices connect, each device must assume a specific role. One device acts 
as the registrar (the device that supplies network and security settings) and the other device acts 
as the enrollee (the device that receives network and security settings. The registrar creates a 
secure EAP (Extensible Authentication Protocol) tunnel and sends the network name (SSID) and the 
WPA2-PSK pre-shared key to the enrollee. If the registrar is already part of a network, it sends the 
existing information. If not, it generates the SSID and WPA2)-PSK randomly.
The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a 
WPS-enabled access point.
