WLAN_TKIP(4)		 BSD Kernel Interfaces Manual		  WLAN_TKIP(4)

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 require‐
     ments of the WPA and 802.11i protocols.  It does encapsulation and decap‐
     sulation 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 automati‐
     cally 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.

SEE ALSO
     wlan(4), wlan_ccmp(4), wlan_wep(4)

STANDARDS
     More information can be found in the IEEE 802.11, WPA, and 802.11i Stan‐
     dards.

HISTORY
     The wlan_tkip driver first appeared in FreeBSD 6.0.
