WPS – WI-FI PROTECTED SETUP
Simple Config Architectural Overview
This section presents a high-level description of the Simple Config architecture. Much of the material is taken
directly from the Simple Config specification.
Figure 1 depicts the major components and their interfaces as defined by Wi-Fi Simple Config Spec. There are
three logical components involved: the Registrar, the access point (AP), and the Enrollee.
The
Enrollee
is a device seeking to join a WLAN domain. Once an Enrollee obtains a valid credential, it
becomes a member.
A
Registrar
is an entity with the authority to issue and revoke domain credentials. A registrar can be
integrated into an AP.
The
AP
can be either a WLAN AP or a wireless router.
Figure 1. Components and Interfaces
Registration initiation is ordinarily accomplished by a user action such as powering up the Enrollee and,
optionally, running a setup wizard on the Registrar (PC).
