Features of WPA Security
The following security features are included in the WPA standard:

WPA Authentication

For environments without a Remote Authentication Dial-In User Service (RADIUS) infrastructure, WPA supports the use of a preshared key. For environments with a RADIUS infrastructure, Extensible Authentication Protocol (EAP) and RADIUS is supported.

Temporal Key Integrity Protocol (TKIP)
For 802.11g, Wired Equivalent Privacy (WEP) encryption is now optional. For WPA, encryption using TKIP is required. TKIP replaces WEP with a new encryption algorithm that is stronger than the WEP algorithm but that uses the calculation facilities present on existing wireless devices to perform encryption operations. TKIP also provides for the following:

·  The verification of the security configuration after the encryption keys are determined.
·  The synchronized changing of the unicast encryption key for each frame.
·  The determination of a unique starting unicast encryption key for each preshared key authentication.

AES Support

WPA defines the use of Advanced Encryption Standard (AES) as an additional replacement for WEP encryption. Because you may not be able to add AES support through a firmware update to existing wireless equipment, support for AES is optional and is dependant on vendor driver support.
