7.10.4.3 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.
