wlan_tkip — TKIP
and Michael crypto support for 802.11 devices
device wlan_tkip
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.
More information can be found in the IEEE 802.11, WPA, and 802.11i Standards.
The wlan_tkip driver first appeared in
FreeBSD 6.0.
