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.
