4.6.4.3 WPA

WPA is the short term for WiFi Protected Access. WPA is an industry-supported, pre-standard

version of 802.11i that utilizes the Temporal Key Integrity Protocol (TKIP), which fixes the

problems of WEP, which includes using dynamic keys. WPA uses a sophiscated key hierarchy

that generates new encryption keys each time a mobile device establishes itself with an AP.

Protocols including 802.1X, EAP, and RADIUS are used for strong authentication. Like WEP,

keys can still be entered manually (pre-shared keys); however, using a RADIUS authentication

server provides automatic key generation and enterprise-wide authentication. WPA uses

temporal key integrity protocol (TKIP) for data encryption. WPA2, also known as 802.11i, uses

advanced encryption standard counter mode CBC-MAC protocol (AES-CCMP) for data

encryption.
