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.
