39 module handles the AES-CCMP cryptographic requirements of the
40 WPA and 802.11i protocols.
42 does encapsulation and decapsulation of CCMP-encoded 802.11 frames
43 and optionally calculates the AES-CCMP cipher.
45 is an 802.11 cryptographic plugin module for use by the
48 This module is automatically loaded if an AES-CCMP key is configured;
49 typically by a WPA supplicant program such as wpa_suplicant,
50 or a WPA authenticator program such as hostapd.
51 Should the underlying network device not be capable of doing the AES-CCMP
52 calculations in hardware, the
54 module will do the work.
60 More information can be found in the IEEE 802.11, WPA, and 802.11i Standards.
