- 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.
module is an 802.11 cryptographic plugin module for use by the
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.
More information can be found in the IEEE 802.11, WPA, and 802.11i Standards.
