Wi-Fi Protected Access 2 (WPA2) Overview

The IEEE 802.11i standard formally replaces Wired Equivalent Privacy (WEP) and the other security features of the original IEEE 802.11 standard. WPA2™ is a product certification available through the Wi-Fi Alliance that certifies wireless equipment as being compatible with the 802.11i standard. The goal of WPA2 certification is to support the additional mandatory security features of the 802.11i standard that are not already included for products that support WPA. Like WPA, WPA2 offers both Enterprise and Personal modes of operation.

Microsoft has released Wi-Fi Protected Access 2 (WPA2)/Wireless Provisioning Services Information Element (WPS IE) update for Windows XP with Service Pack 2, a free download that updates the wireless client components in Windows XP with Service Pack 2 to support WPA2. This article describes the features of WPA2 security and the support for WPA2 included with the WPA2/WPS IE update for Windows XP with Service Pack 2.
