NAME
wlan_ccmp —
AES-CCMP crypto support for 802.11 devices
SYNOPSIS
device wlan_ccmp
DESCRIPTION
Thewlan_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.
