wlan_gcmp4

Usage

Overview

The wlan_gcmp module handles the Galois/Counter Mode Protocol cryptographic 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; 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-GCMP calculations in hardware, the wlan_gcmp module will do the work.
