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.
