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.
