AES-CCMP crypto support for 802.11 devices
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
module is an 802.11 cryptographic plugin module for use by the
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
. Should the underlying network device not be capable of doing the AES-CCMP calculations in hardware, the
module will do the work.
STANDARDS More information can be found in the IEEE 802.11, WPA, and 802.11i Standards.
