wlan_ccmp —
AES-CCMP crypto support for 802.11 devices
device wlan_ccmp
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.
More information can be found in the IEEE 802.11, WPA, and 802.11i Standards.
The wlan_ccmp driver first appeared in
FreeBSD 6.0.
