NAME¶
wlan_tkip
—
TKIP and Michael crypto support for 802.11
devices
SYNOPSIS¶
device wlan_tkip
DESCRIPTION¶
The
wlan_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.
