8 HOSTAPD and Wi-Fi Protected Setup (WPS)
This section describes how the WPS implementation in hostapd can be configured and how an external component
on an AP is used to enable enrollment of client devices.
WPS uses the following terms to describe the entities participating in the network setup:
Access Point: WLAN access point
Registrar: A device that controls a network and can authorize addition of new devices. This may be either in the AP
("internal Registrar") or in an external device, e.g., a laptop, ("external Registrar")
Enrollee: A device that is being authorized to use the network
It should also be noted that the AP and a client device may change roles (i.e., AP acts as an Enrollee and client
device as a Registrar) when WPS is used to configure the access point.)
8.1 Hostapd Configuration before Compilation
WPS component needs to be enabled in hostapd build configuration (.config)
i.e: vim host/wlan/hostapd-2.3/hostapd/.config
Ensure that the below mentioned entities are enabled in .config file
