Wi-Fi Simple Configuration
Simple Config Task Group
Formed Aug 2004
Focus is Home WLAN
Set-up (WPA-Personal)
Strong WFA interest and
participation – 9 companies
submitted 6 proposals
Seven companies formed
7C group to converge on
one proposal.
7C proposal selected on
Feb 8, 2006
First WFA compliance plug fest
had strong participation

Wi-Fi Simple Config Features
Transport Independent Registration
(EAP, UPnP, UFD, NFC)
Uses Authenticated Diffie-Hellman Exchange
Default method uses a random PIN
Options include UFD, NFC, PBC
UPnP Management interface permits Registrars to
securely configure AP settings
Supports multiple registrars, not just PC (cell phone,
TV, AP, etc.)
Support for legacy APs
Specification includes many extensibility features
Registration Protocol
Protocol exchange between
Registrar and Enrollee
Exchanges DH Keys
Two-way Authentication
Transfer of Configuration
Characteristics
Transport Independent (EAP, UPnP,
UFD, and NFC)
Lock-step message validation
Detects invalid PIN/PW
AP Management Interface

Authenticated UPnP Actions
PutMessage (for Ethernet)
GetAPSettings, SetAPSettings, DelAPSettings
GetSTASettings, SetSTASettings
RebootAP, ResetAP, RebootSTA, ResetSTA
SOAP layer is very simple, parameters are base64-encoded using
same binary format as EAP message data
Wi-Fi Simple Config Requirements
AP
WFA IE in beacons, probe responses
WFA EAP method, no RADIUS required
WFA UPnP device
May include built-in Registrar
STA (Enrollee)
WFA IE in probe requests
802.1X supplicant and PIN for WFA EAP method
May support one or more OOB channels or Push-Button
Registrar (no formal WFA requirements…)
UPnP control point for AP management interface
In-band Registration Protocol over EAP and/or UPnP
May support one or more OOB channels or Push-Button
May support Registration Protocol over ad hoc
All: Diffie-Hellman, HMAC-SHA-256, AES-CBC

UFD
Windows Connect Now
MTP
WCN-MTP provides mechanism to transfer
settings or associate devices using a USB
Cable
Wi-Fi settings can be transferred to a Digital Still
Camera over USB
Uses same XML schema as WCN-UFD
WCN-UFD does not require any encryption
and is secure by default
Windows Connect Now
NET
Allows transfer of settings over Ethernet
(Out of Band)/Wi-Fi (In Band) to create a
secured wireless network
Uses existing capabilities of devices with
wired/wireless network interfaces
Provides the ability to configure the device with
Plug and Play experience in Windows Vista
Windows Connect Now
NET
Allows transfer of settings over Wi-Fi (In Band) to
create a secured wireless network
Wireless settings encrypted using PIN
In-Band method requires no additional interfaces
for configuration
Provides the ability to configure the device with
Plug and Play experience in Windows Vista
(when proxied by WCN Access Point)
