3.4.3 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 WPA-PSK or WPA2-PSK pre-shared key to the enrollee. Whether WPA-PSK
or WPA2-PSK is used depends on the standards supported by the devices. If the registrar is
already part of a network, it sends the existing information. If not, it generates the SSID and
WPA(2)-PSK randomly.
