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.
