.Nd AES-CCMP crypto support for 802.11 devices
|

.Sh SYNOPSIS
|
|
|
|
|
.Cd "device wlan_ccmp"
|
|
|
|
|
.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
module handles the AES-CCMP cryptographic requirements of the
|
|
|
|
|
WPA and 802.11i protocols.
|
2005-01-13 11:09:58 +00:00
|
|
|
It does encapsulation and decapsulation of CCMP-encoded 802.11 frames
|
2004-12-08 17:47:32 +00:00
|
|
|
and optionally calculates the AES-CCMP cipher.
|
2005-01-13 11:09:58 +00:00
|
|
|
The
|
2004-12-08 17:47:32 +00:00
|
|
|
.Nm
|
2005-01-13 11:09:58 +00:00
|
|
|
module is an 802.11 cryptographic plugin module for use by the
|
2004-12-08 17:47:32 +00:00
|
|
|
.Xr wlan 4
|
|
|
|
|
module.
|
|
|
|
|
This module is automatically loaded if an AES-CCMP key is configured;
|
2004-12-09 13:57:12 +00:00
|
|
|
typically by a WPA supplicant program such as wpa_supplicant,
|
2005-01-13 11:09:58 +00:00
|
|
|
or a WPA authenticator program such as
|
|
|
|
|
.Nm hostapd .
|
2004-12-08 17:47:32 +00:00
|
|
|
Should the underlying network device not be capable of doing the AES-CCMP
|
|
|
|
|
calculations in hardware, the
|
|
|
|
|
.Nm
|
|
|
|
|
module will do the work.
