WLAN_GCMP(4) Kernel Interfaces Manual WLAN_GCMP(4) NAME wlan_gcmp -- AES-GCMP crypto support for 802.11 devices SYNOPSIS device wlan_gcmp DESCRIPTION The wlan_gcmp module handles the Galois/Counter Mode Protocol crypto- graphic requirements of the IEEE 802.11ad and WPA2/WPA3 protocols. It does encapsulation and decapsulation of GCMP-encoded 802.11 frames and optionally calculates the AES-GCMP cipher. The wlan_gcmp module is an 802.11 cryptographic plugin module for use by the wlan(4) module. This module is automatically loaded if an AES-GCMP key is configured; typi- cally by a WPA supplicant program such as wpa_supplicant, or a WPA au- thenticator program such as hostapd. Should the underlying network de- vice not be capable of doing the AES-GCMP calculations in hardware, the wlan_gcmp module will do the work. SEE ALSO wlan(4), wlan_ccmp(4), wlan_tkip(4), wlan_wep(4) STANDARDS More information can be found in the IEEE 802.11, and WPA Standards. HISTORY The wlan_gcmp driver first appeared in FreeBSD 15.0. FreeBSD 15.0 June 13, 2025 WLAN_GCMP(4)
