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.

STANDARDS¶
More information can be found in the IEEE 802.11, WPA, and 802.11i Standards.
HISTORY¶
The
wlan_ccmp driver first appeared in
FreeBSD 6.0.
