NAME

wlan_ccmp - AES-CCMP crypto support for 802.11 devices

SYNOPSIS

device wlan_ccmp

DESCRIPTION

The ifconfig module handles the AES-CCMP cryptographic requirements of the WPA and 802.11i protocols. It does encapsulation and decapsulation of CCMP-encoded 802.11 frames and optionally calculates the AES-CCMP cipher. The ifconfig module is an 802.11 cryptographic plugin module for use by the wlan(4) module. This module is automatically loaded if an AES-CCMP 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 AES-CCMP calculations in hardware, the ifconfig module will do the work.
