wlan_ccmp(4)
AES-CCMP crypto support for 802.11 devices
SYNOPSIS
device wlan_ccmp
DESCRIPTION
The
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
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
module will do the work.
STANDARDS
More information can be found in the IEEE 802.11, WPA, and 802.11i Standards.
HISTORY
The
driver first appeared in
Fx 6.0 .
