hostapd and Wi-Fi Protected Setup (WPS)
|
|
|
|
=======================================
|
|
|
|
|
|
|
|
This document describes how the WPS implementation in hostapd can be
|
|
|
|
configured and how an external component on an AP (e.g., web UI) is
|
|
|
|
used to enable enrollment of client devices.

Introduction to WPS
|
|
|
|
-------------------
|
|
|
|
|
|
|
|
Wi-Fi Protected Setup (WPS) is a mechanism for easy configuration of a
|
|
|
|
wireless network. It allows automated generation of random keys (WPA
|
|
|
|
passphrase/PSK) and configuration of an access point and client
|
|
|
|
devices. WPS includes number of methods for setting up connections
|
|
|
|
with PIN method and push-button configuration (PBC) being the most
|
|
|
|
commonly deployed options.
|
|
|
|
|
|
|
|
While WPS can enable more home networks to use encryption in the
|
|
|
|
wireless network, it should be noted that the use of the PIN and
|
|
|
|
especially PBC mechanisms for authenticating the initial key setup is
|
|
|
|
not very secure. As such, use of WPS may not be suitable for
|
|
|
|
environments that require secure network access without chance for
|
|
|
|
allowing outsiders to gain access during the setup phase.
|
|
|
|
|
|
|
|
WPS uses following terms to describe the entities participating in the
|
|
|
|
network setup:
|
|
|
|
- access point: the WLAN access point
|
|
|
|
- Registrar: a device that control 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.
|
|
|
|
|

hostapd implementation
|
|
|
|
----------------------
|
|
|
|
|
|
|
|
hostapd includes an optional WPS component that can be used as an
|
|
|
|
internal WPS Registrar to manage addition of new WPS enabled clients
|
|
|
|
to the network. In addition, WPS Enrollee functionality in hostapd can
|
|
|
|
be used to allow external WPS Registrars to configure the access
|
|
|
|
point, e.g., for initial network setup. In addition, hostapd can proxy a
|
|
|
|
WPS registration between a wireless Enrollee and an external Registrar
|
|
|
|
(e.g., Microsoft Vista or Atheros JumpStart) with UPnP.

hostapd configuration
|
|
|
|
---------------------
|
|
|
|
|
|
|
|
WPS is an optional component that needs to be enabled in hostapd build
|
|
|
|
configuration (.config). Here is an example configuration that
|
2015-04-18 05:04:12 +00:00

2012-05-10 - v1.0
* Add channel selection support in hostapd. See hostapd.conf.
* Add support for IEEE 802.11v Time Advertisement mechanism with UTC
TSF offset. See hostapd.conf for config info.
* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
This allows the driver to use PS buffering of Deauthentication and
Disassociation frames when the STA is in power save sleep. Only
available with drivers that provide TX status events for Deauth/
Disassoc frames (nl80211).
* Allow PMKSA caching to be disabled on the Authenticator. See

* atheros: Add support for IEEE 802.11w configuration.
* bsd: Add support for setting HT values in IFM_MMASK.
* Allow client isolation to be configured with ap_isolate. Client
isolation can be used to prevent low-level bridging of frames
between associated stations in the BSS. By default, this bridging
is allowed.
* Allow coexistance of HT BSSes with WEP/TKIP BSSes.
* Add require_ht config parameter, which can be used to configure
hostapd to reject association with any station that does not support
HT PHY.
* Add support for writing debug log to a file using "-f" option. Also
add relog CLI command to re-open the log file.
* Add bridge handling for WDS STA interfaces. By default they are
added to the configured bridge of the AP interface (if present),
but the user can also specify a separate bridge using cli command
wds_bridge.
* hostapd_cli:
- Add wds_bridge command for specifying bridge for WDS STA
interfaces.
- Add relog command for reopening log file.
- Send AP-STA-DISCONNECTED event when an AP disconnects a station
due to inactivity.
- Add wps_config ctrl_interface command for configuring AP. This
command can be used to configure the AP using the internal WPS
registrar. It works in the same way as new AP settings received
from an ER.
- Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
- Add command get version, that returns hostapd version string.
* WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
notification to the STA.
* Allow AP mode to disconnect STAs based on low ACK condition (when
the data connection is not working properly, e.g., due to the STA
going outside the range of the AP). Disabled by default, enable by
config option disassoc_low_ack.
* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
config file.
* WPS:
- Send AP Settings as a wrapped Credential attribute to ctrl_iface
in WPS-NEW-AP-SETTINGS.
- Dispatch more WPS events through hostapd ctrl_iface.
- Add mechanism for indicating non-standard WPS errors.
- Change concurrent radio AP to use only one WPS UPnP instance.
- Add wps_check_pin command for processing PIN from user input.
UIs can use this command to process a PIN entered by a user and to
validate the checksum digit (if present).
- Add hostap_cli get_config command to display current AP config.
- Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
runtime and support dynamic AP PIN management.
- Disable AP PIN after 10 consecutive failures. Slow down attacks
on failures up to 10.
- Allow AP to start in Enrollee mode without AP PIN for probing,
to be compatible with Windows 7.
- Add Config Error into WPS-FAIL events to provide more info
to the user on how to resolve the issue.
- When controlling multiple interfaces:
- apply WPS commands to all interfaces configured to use WPS
- apply WPS config changes to all interfaces that use WPS
- when an attack is detected on any interface, disable AP PIN on
all interfaces
* WPS ER:
- Show SetSelectedRegistrar events as ctrl_iface events.
- Add special AP Setup Locked mode to allow read only ER.
ap_setup_locked=2 can now be used to enable a special mode where
WPS ER can learn the current AP settings, but cannot change them.
* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
- Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
for testing protocol extensibility.
- Add build option CONFIG_WPS_STRICT to allow disabling of WPS
workarounds.
- Add support for AuthorizedMACs attribute.
* TDLS:
- Allow TDLS use or TDLS channel switching in the BSS to be
prohibited in the BSS, using config params tdls_prohibit and
tdls_prohibit_chan_switch.
* EAP server: Add support for configuring fragment size (see
fragment_size in hostapd.conf).
* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
wlantest can be used to capture frames from a monitor interface
for realtime capturing or from pcap files for offline analysis.
* Interworking: Support added for 802.11u. Enable in .config with
CONFIG_INTERWORKING. See hostapd.conf for config parameters for
interworking.
* Android: Add build and runtime support for Android hostapd.
* Add a new debug message level for excessive information. Use
-ddd to enable.
* TLS: Add support for tls_disable_time_checks=1 in client mode.
* Internal TLS:
- Add support for TLS v1.1 (RFC 4346). Enable with build parameter
CONFIG_TLSV11.
- Add domainComponent parser for X.509 names
* Reorder some IEs to get closer to IEEE 802.11 standard. Move
WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
Move HT IEs to be later in (Re)Assoc Resp.
* Many bugfixes.

WPS requires either a device PIN code (usually, 8-digit number) or a
|
|
|
|
pushbutton event (for PBC) to allow a new WPS Enrollee to join the
|
|
|
|
network. hostapd uses the control interface as an input channel for

these events.

The PIN value used in the commands must be processed by an UI to
|
|
|
|
remove non-digit characters and potentially, to verify the checksum
|
|
|
|
digit. "hostapd_cli wps_check_pin <PIN>" can be used to do such
|
|
|
|
processing. It returns FAIL if the PIN is invalid, or FAIL-CHECKSUM if
|
|
|
|
the checksum digit is incorrect, or the processed PIN (non-digit
|
|
|
|
characters removed) if the PIN is valid.
|
|
|
|
|
2010-10-29 09:21:40 +00:00
|
|
|
When a client device (WPS Enrollee) connects to hostapd (WPS
|
|
|
|
Registrar) in order to start PIN mode negotiation for WPS, an
|
|
|
|
identifier (Enrollee UUID) is sent. hostapd will need to be configured
|
|
|
|
with a device password (PIN) for this Enrollee. This is an operation
|
|
|
|
that requires user interaction (assuming there are no pre-configured
|
|
|
|
PINs on the AP for a set of Enrollee).
|
|
|
|
|
|
|
|
The PIN request with information about the device is appended to the
|
|
|
|
wps_pin_requests file (/var/run/hostapd.pin-req in this example). In
|
|
|
|
addition, hostapd control interface event is sent as a notification of
|
|
|
|
a new device. The AP could use, e.g., a web UI for showing active
|
|
|
|
Enrollees to the user and request a PIN for an Enrollee.
|
|
|
|
|
|
|
|
The PIN request file has one line for every Enrollee that connected to
|
|
|
|
the AP, but for which there was no PIN. Following information is
|
|
|
|
provided for each Enrollee (separated with tabulators):
|
|
|
|
- timestamp (seconds from 1970-01-01)
|
|
|
|
- Enrollee UUID
|
|
|
|
- MAC address
|
|
|
|
- Device name
|
|
|
|
- Manufacturer
|
|
|
|
- Model Name
|
|
|
|
- Model Number
|
|
|
|
- Serial Number
|
|
|
|
- Device category
|
|
|
|
|
|
|
|
Example line in the /var/run/hostapd.pin-req file:
|
|
|
|
1200188391 53b63a98-d29e-4457-a2ed-094d7e6a669c Intel(R) Centrino(R) Intel Corporation Intel(R) Centrino(R) - - 1-0050F204-1
|
|
|
|
|
|
|
|
Control interface data:
|
|
|
|
WPS-PIN-NEEDED [UUID-E|MAC Address|Device Name|Manufacturer|Model Name|Model Number|Serial Number|Device Category]
|
|
|
|
For example:
|
|
|
|
<2>WPS-PIN-NEEDED [53b63a98-d29e-4457-a2ed-094d7e6a669c|02:12:34:56:78:9a|Device|Manuf|Model|Model Number|Serial Number|1-0050F204-1]
|
|
|
|
|
|
|
|
When the user enters a PIN for a pending Enrollee, e.g., on the web
|
|
|
|
UI), hostapd needs to be notified of the new PIN over the control
|
|
|
|
interface. This can be done either by using the UNIX domain socket
|
|
|
|
-based control interface directly (src/common/wpa_ctrl.c provides
|
|
|
|
helper functions for using the interface) or by calling hostapd_cli.
|
|
|
|
|
|
|
|
Example command to add a PIN (12345670) for an Enrollee:
|
|
|
|
|
|
|
|
hostapd_cli wps_pin 53b63a98-d29e-4457-a2ed-094d7e6a669c 12345670
|
|
|
|
|
|
|
|
If the UUID-E is not available (e.g., Enrollee waits for the Registrar
|
|
|
|
to be selected before connecting), wildcard UUID may be used to allow
|
|
|
|
the PIN to be used once with any UUID:
|
|
|
|
|
|
|
|
hostapd_cli wps_pin any 12345670
|
|
|
|
|
|
|
|
To reduce likelihood of PIN being used with other devices or of
|
|
|
|
forgetting an active PIN available for potential attackers, expiration
|

After this, the Enrollee can connect to the AP again and complete WPS
|
|
|
|
negotiation. At that point, a new, random WPA PSK is generated for the
|
|
|
|
client device and the client can then use that key to connect to the
|
|
|
|
AP to access the network.
|
|
|
|
|
|
|
|
|
|
|
|
If the AP includes a pushbutton, WPS PBC mode can be used. It is
|
|
|
|
enabled by pushing a button on both the AP and the client at about the
|
|
|
|
same time (2 minute window). hostapd needs to be notified about the AP
|
|
|
|
button pushed event over the control interface, e.g., by calling
|
|
|
|
hostapd_cli:
|
|
|
|
|
|
|
|
hostapd_cli wps_pbc
|
|
|
|
|
|
|
|
At this point, the client has two minutes to complete WPS negotiation
|
|
|
|
which will generate a new WPA PSK in the same way as the PIN method
|
|
|
|
described above.
|
|
|
|
|
|
|
|
|
|
|
|
When an external Registrar is used, the AP can act as an Enrollee and
|
|
|
|
use its AP PIN. A static AP PIN (e.g., one one a label in the AP
|
|
|
|
device) can be configured in hostapd.conf (ap_pin parameter). A more
|
|
|
|
secure option is to use hostapd_cli wps_ap_pin command to enable the
|
|
|
|
AP PIN only based on user action (and even better security by using a
|
|
|
|
random AP PIN for each session, i.e., by using "wps_ap_pin random"
|
|
|
|
command with a timeout value). Following commands are available for
|
|
|
|
managing the dynamic AP PIN operations:
|
|
|
|
|
|
|
|
hostapd_cli wps_ap_pin disable
|
|
|
|
- disable AP PIN (i.e., do not allow external Registrars to use it to
|
|
|
|
learn the current AP settings or to reconfigure the AP)
|
|
|
|
|
|
|
|
hostapd_cli wps_ap_pin random [timeout]
|
|
|
|
- generate a random AP PIN and enable it
|
|
|
|
- if the optional timeout parameter is given, the AP PIN will be enabled
|
|
|
|
for the specified number of seconds
|
|
|
|
|
|
|
|
hostapd_cli wps_ap_pin get
|
|
|
|
- fetch the current AP PIN
|
|
|
|
|
|
|
|
hostapd_cli wps_ap_pin set <PIN> [timeout]
|
|
|
|
- set the AP PIN and enable it
|
|
|
|
- if the optional timeout parameter is given, the AP PIN will be enabled
|
|
|
|
for the specified number of seconds

- Add command get version, that returns hostapd version string.
* WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
notification to the STA.
* Allow AP mode to disconnect STAs based on low ACK condition (when
the data connection is not working properly, e.g., due to the STA
going outside the range of the AP). Disabled by default, enable by
config option disassoc_low_ack.
* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
config file.

- Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
runtime and support dynamic AP PIN management.
- Disable AP PIN after 10 consecutive failures. Slow down attacks
on failures up to 10.
- Allow AP to start in Enrollee mode without AP PIN for probing,
to be compatible with Windows 7.
- Add Config Error into WPS-FAIL events to provide more info
to the user on how to resolve the issue.
- When controlling multiple interfaces:
- apply WPS commands to all interfaces configured to use WPS
- apply WPS config changes to all interfaces that use WPS
- when an attack is detected on any interface, disable AP PIN on
all interfaces
* WPS ER:
- Show SetSelectedRegistrar events as ctrl_iface events.
- Add special AP Setup Locked mode to allow read only ER.
ap_setup_locked=2 can now be used to enable a special mode where
WPS ER can learn the current AP settings, but cannot change them.
* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
- Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
for testing protocol extensibility.
- Add build option CONFIG_WPS_STRICT to allow disabling of WPS
workarounds.

prohibited in the BSS, using config params tdls_prohibit and
tdls_prohibit_chan_switch.
* EAP server: Add support for configuring fragment size (see
fragment_size in hostapd.conf).
* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
wlantest can be used to capture frames from a monitor interface
for realtime capturing or from pcap files for offline analysis.
* Interworking: Support added for 802.11u. Enable in .config with
CONFIG_INTERWORKING. See hostapd.conf for config parameters for
interworking.
* Android: Add build and runtime support for Android hostapd.

Credential generation and configuration changes
|
|
|
|
-----------------------------------------------
|
|
|
|
|
|
|
|
By default, hostapd generates credentials for Enrollees and processing
|
|
|
|
AP configuration updates internally. However, it is possible to
|
|
|
|
control these operations from external programs, if desired.
|
|
|
|
|
|
|
|
The internal credential generation can be disabled with
|
|
|
|
skip_cred_build=1 option in the configuration. extra_cred option will
|
|
|
|
then need to be used to provide pre-configured Credential attribute(s)
|
|
|
|
for hostapd to use. The exact data from this binary file will be sent,
|
|
|
|
i.e., it will have to include valid WPS attributes. extra_cred can
|
|
|
|
also be used to add additional networks if the Registrar is used to
|
|
|
|
configure credentials for multiple networks.
|
|
|
|
|
|
|
|
Processing of received configuration updates can be disabled with
|
|
|
|
wps_cred_processing=1 option. When this is used, an external program
|
|
|
|
is responsible for creating hostapd configuration files and processing
|
|
|
|
configuration updates based on messages received from hostapd over
|
|
|
|
control interface. This will also include the initial configuration on
|
|
|
|
first successful registration if the AP is initially set in
|
|
|
|
unconfigured state.
|
|
|
|
|
|
|
|
Following control interface messages are sent out for external programs:
|
|
|
|
|
|
|
|
WPS-REG-SUCCESS <Enrollee MAC address <UUID-E>
|
|
|
|
For example:
|
|
|
|
<2>WPS-REG-SUCCESS 02:66:a0:ee:17:27 2b7093f1-d6fb-5108-adbb-bea66bb87333

This can be used to update the externally stored AP configuration and
|
|
|
|
then update hostapd configuration (followed by restarting of hostapd).
|
Import wpa_supplicant / hostapd 2.0.

2012-05-10 - v1.0
* Add channel selection support in hostapd. See hostapd.conf.
* Add support for IEEE 802.11v Time Advertisement mechanism with UTC
TSF offset. See hostapd.conf for config info.
* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
This allows the driver to use PS buffering of Deauthentication and
Disassociation frames when the STA is in power save sleep. Only
available with drivers that provide TX status events for Deauth/
Disassoc frames (nl80211).
* Allow PMKSA caching to be disabled on the Authenticator. See
hostap.conf config parameter disable_pmksa_caching.
* atheros: Add support for IEEE 802.11w configuration.
* bsd: Add support for setting HT values in IFM_MMASK.
* Allow client isolation to be configured with ap_isolate. Client
isolation can be used to prevent low-level bridging of frames
between associated stations in the BSS. By default, this bridging
is allowed.
* Allow coexistance of HT BSSes with WEP/TKIP BSSes.
* Add require_ht config parameter, which can be used to configure
hostapd to reject association with any station that does not support
HT PHY.
* Add support for writing debug log to a file using "-f" option. Also
add relog CLI command to re-open the log file.
* Add bridge handling for WDS STA interfaces. By default they are
added to the configured bridge of the AP interface (if present),
but the user can also specify a separate bridge using cli command
wds_bridge.
* hostapd_cli:
- Add wds_bridge command for specifying bridge for WDS STA
interfaces.
- Add relog command for reopening log file.
- Send AP-STA-DISCONNECTED event when an AP disconnects a station
due to inactivity.
- Add wps_config ctrl_interface command for configuring AP. This
command can be used to configure the AP using the internal WPS
registrar. It works in the same way as new AP settings received
from an ER.
- Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
- Add command get version, that returns hostapd version string.
* WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
notification to the STA.
* Allow AP mode to disconnect STAs based on low ACK condition (when
the data connection is not working properly, e.g., due to the STA
going outside the range of the AP). Disabled by default, enable by
config option disassoc_low_ack.
* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
config file.
* WPS:
- Send AP Settings as a wrapped Credential attribute to ctrl_iface
in WPS-NEW-AP-SETTINGS.
- Dispatch more WPS events through hostapd ctrl_iface.
- Add mechanism for indicating non-standard WPS errors.
- Change concurrent radio AP to use only one WPS UPnP instance.
- Add wps_check_pin command for processing PIN from user input.
UIs can use this command to process a PIN entered by a user and to
validate the checksum digit (if present).
- Add hostap_cli get_config command to display current AP config.
- Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
runtime and support dynamic AP PIN management.
- Disable AP PIN after 10 consecutive failures. Slow down attacks
on failures up to 10.
- Allow AP to start in Enrollee mode without AP PIN for probing,
to be compatible with Windows 7.
- Add Config Error into WPS-FAIL events to provide more info
to the user on how to resolve the issue.
- When controlling multiple interfaces:
- apply WPS commands to all interfaces configured to use WPS
- apply WPS config changes to all interfaces that use WPS
- when an attack is detected on any interface, disable AP PIN on
all interfaces
* WPS ER:
- Show SetSelectedRegistrar events as ctrl_iface events.
- Add special AP Setup Locked mode to allow read only ER.
ap_setup_locked=2 can now be used to enable a special mode where
WPS ER can learn the current AP settings, but cannot change them.
* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
- Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
for testing protocol extensibility.
- Add build option CONFIG_WPS_STRICT to allow disabling of WPS
workarounds.
- Add support for AuthorizedMACs attribute.
* TDLS:
- Allow TDLS use or TDLS channel switching in the BSS to be
prohibited in the BSS, using config params tdls_prohibit and
tdls_prohibit_chan_switch.
* EAP server: Add support for configuring fragment size (see
fragment_size in hostapd.conf).
* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
wlantest can be used to capture frames from a monitor interface
for realtime capturing or from pcap files for offline analysis.
* Interworking: Support added for 802.11u. Enable in .config with
CONFIG_INTERWORKING. See hostapd.conf for config parameters for
interworking.
* Android: Add build and runtime support for Android hostapd.
* Add a new debug message level for excessive information. Use
-ddd to enable.
* TLS: Add support for tls_disable_time_checks=1 in client mode.
* Internal TLS:
- Add support for TLS v1.1 (RFC 4346). Enable with build parameter
CONFIG_TLSV11.
- Add domainComponent parser for X.509 names
* Reorder some IEs to get closer to IEEE 802.11 standard. Move
WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
Move HT IEs to be later in (Re)Assoc Resp.
* Many bugfixes.

WPS with NFC
|
|
|
|
------------
|
|
|
|
|
|
|
|
WPS can be used with NFC-based configuration method. An NFC tag
|
|
|
|
containing a password token from the Enrollee can be used to
|
|
|
|
authenticate the connection instead of the PIN. In addition, an NFC tag
|
|
|
|
with a configuration token can be used to transfer AP settings without
|
|
|
|
going through the WPS protocol.
|
|
|
|
|
|
|
|
When the AP acts as an Enrollee, a local NFC tag with a password token
|
|
|
|
can be used by touching the NFC interface of an external Registrar. The
|
|
|
|
wps_nfc_token command is used to manage use of the NFC password token
|
|
|
|
from the AP. "wps_nfc_token enable" enables the use of the AP's NFC
|
|
|
|
password token (in place of AP PIN) and "wps_nfc_token disable" disables
|
|
|
|
the NFC password token.
|
|
|
|
|
|
|
|
The NFC password token that is either pre-configured in the
|
|
|
|
configuration file (wps_nfc_dev_pw_id, wps_nfc_dh_pubkey,
|
|
|
|
wps_nfc_dh_privkey, wps_nfc_dev_pw) or generated dynamically with
|
|
|
|
"wps_nfc_token <WPS|NDEF>" command. The nfc_pw_token tool from
|
|
|
|
wpa_supplicant can be used to generate NFC password tokens during
|
|
|
|
manufacturing (each AP needs to have its own random keys).
|
|
|
|
|
|
|
|
The "wps_nfc_config_token <WPS/NDEF>" command can be used to build an
|
|
|
|
NFC configuration token. The output value from this command is a hexdump
|
|
|
|
of the current AP configuration (WPS parameter requests this to include
|
|
|
|
only the WPS attributes; NDEF parameter requests additional NDEF
|
|
|
|
encapsulation to be included). This data needs to be written to an NFC
|
|
|
|
tag with an external program. Once written, the NFC configuration token
|
|
|
|
can be used to touch an NFC interface on a station to provision the
|
|
|
|
credentials needed to access the network.
|
|
|
|
|
|
|
|
When the NFC device on the AP reads an NFC tag with a MIME media type
|
|
|
|
"application/vnd.wfa.wsc", the NDEF message payload (with or without
|
|
|
|
NDEF encapsulation) can be delivered to hostapd using the
|
|
|
|
following hostapd_cli command:
|
|
|
|
|
|
|
|
wps_nfc_tag_read <hexdump of payload>
|
|
|
|
|
|
|
|
If the NFC tag contains a password token, the token is added to the
|
|
|
|
internal Registrar. This allows station Enrollee from which the password
|
|
|
|
token was received to run through WPS protocol to provision the
|
|
|
|
credential.

|
|
|
|
|
|
|
"nfc_get_handover_sel <NDEF> <WPS>" command can be used to build the
|
|
|
|
contents of a Handover Select Message for connection handover when this
|
|
|
|
does not depend on the contents of the Handover Request Message. The
|
|
|
|
first argument selects the format of the output data and the second
|
|
|
|
argument selects which type of connection handover is requested (WPS =
|
|
|
|
Wi-Fi handover as specified in WSC 2.0).
|
|
|
|
|
|
|
|
"nfc_report_handover <INIT/RESP> WPS <carrier from handover request>
|
|
|
|
<carrier from handover select>" is used to report completed NFC
|
|
|
|
connection handover. The first parameter indicates whether the local
|
|
|
|
device initiated or responded to the connection handover and the carrier
|
|
|
|
records are the selected carrier from the handover request and select
|
|
|
|
messages as a hexdump.
