Configuring WLAN Security
Wi-Fi Protected Access (WPA) is an encryption scheme specified in the IEEE Wireless Fidelity (Wi-Fi) standard,
802.11i. WPA provides more sophisticated data encryption than WEP. WPA is designed for corporate networks and
small-business environments where more wireless traffic allows quicker discovery of encryption keys by an
unauthorized person.
The encryption method is Temporal Key Integrity Protocol (TKIP). TKIP addresses WEP's weaknesses with a re-keying
mechanism, a per-packet mixing function, a message integrity check, and an extended initialization vector, however
TKIP also has vulnerabilities.
Wi-Fi Protected Access 2 (WPA2) is an enhanced version of WPA. WPA2 uses the Advanced Encryption Standard
(AES) instead of TKIP. AES supports 128-bit, 192-bit and 256-bit keys. WPA/WPA2 also provide strong user
authentication based on 802.1x EAP.
