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.
