WLAN_CCMP(4)		    Kernel Interfaces Manual		  WLAN_CCMP(4)

NAME
       wlan_ccmp -- AES-CCMP crypto support for	802.11 devices

SYNOPSIS
       device wlan_ccmp

DESCRIPTION
       The wlan_ccmp module handles the	AES-CCMP cryptographic requirements of
       the WPA and 802.11i protocols.  It does encapsulation and decapsulation
       of  CCMP-encoded	 802.11	 frames	and optionally calculates the AES-CCMP
       cipher.	The wlan_ccmp module is	an 802.11 cryptographic	plugin	module
       for  use	by the wlan(4) module.	This module is automatically loaded if
       an AES-CCMP key is configured; typically	by a  WPA  supplicant  program
       such as wpa_supplicant, or a WPA	authenticator program such as hostapd.
       Should  the  underlying network device not be capable of	doing the AES-
       CCMP calculations in hardware, the wlan_ccmp module will	do the work.

SEE ALSO
       wlan(4),	wlan_tkip(4), wlan_wep(4)

STANDARDS
       More information	can be found in	the  IEEE  802.11,  WPA,  and  802.11i
       Standards.

HISTORY
       The wlan_ccmp driver first appeared in FreeBSD 6.0.

FreeBSD	14.3		       December	7, 2004			  WLAN_CCMP(4)
