NAME
wlan_tkip —
TKIP and Michael crypto support for
802.11 devices
SYNOPSIS
device wlan_tkip
DESCRIPTION
Thewlan_tkip module handles the TKIP and Michael
cryptographic requirements of the WPA and 802.11i protocols. It does
encapsulation and decapsulation of TKIP-encoded 802.11 frames and optionally
calculates the TKIP cipher and Michael MIC. The
wlan_tkip module is an 802.11 cryptographic plugin
module for use by the
wlan(4) module. This module is automatically loaded if a TKIP 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 TKIP and/or Michael
calculations in hardware, the wlan_tkip module will do
the work.
