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. The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a WPS-enabled access point.

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.
The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a
WPS-enabled access point.
