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 re
quirements 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.
