CCMP
Based on the Advanced Encryption Standard (AES) defined in the National Institute of Standards and
Technology's FIPS Publication 197, AES-CCMP is a symmetric block cipher that can encrypt and
decrypt data using keys of 128, 192, and 256 bits. AES-CCMP is superior to WEP encryption and is
defined in the IEEE 802.11i standard.

EAP
Extensible Authentication Protocol. A protocol that WPA uses to authorize user access to wireless
networks. Common implementations include EAP-FAST and EAP-MD5.
EAP-FAST
EAP-FAST is a two-phase implementation of the EAP authentic ation protocol:
•
Phase 0, provisioning. Provision client with a credential called PAC (Protected Access
Credentials).
•
Phase 1, authentication. Use the PAC to establish a tunnel with the server and authenticate the
username and password.
See also AAA and EAP.
EAP-MD5 server
Servers that use EAP to provide dynamic, session-specific wireless encryption keys, central user
administration, and authentication between clients and access points. EAP-MD5 uses MD5 hashing on
client and challenge passwords.

PEAP server
Protected EAP server, which combines centralized two-way authentication with dynamically generated
wireless equivalent privacy keys or WEP keys.
