WPS Security
The WPS protocol itself consists as a series of EAP message exchanges that is
triggered by a user action and relies on an exchange of descriptive information that
should precede that user's action.
The descriptive information is transferred through a new IE that's added to the
Beacon, Probe Response and optionally to the Probe Request and Association
Request/Response messages. Other than purely informative TLVs, those IEs will
also hold the possible, and the currently deployed, configuration methods of the
device. The WPS IE, has a type field with a value of '221', and OUI of 00-50-F2-04.
The Data part of the IE is constructed out of TLVs that describe the device and its
capabilities.
After the identification of the device's capabilities on both ends, a human trigger is to
initiate the actual session of the protocol. The session consists of 8 messages, that
are followed in the case of a successful session by a message to indicate the
protocol is done. The exact stream of messages may change when configuring
different kinds of devices (AP or STA) or using different physical media (wired or
wireless).
