Microsoft download center recently added a patch to enable WPA2 capabilities to Windows XP SP2. WPA2 or Wi-Fi Protected Access 2. Microsoft claims that this update enhances the Windows XP wireless client software with support for the new Wi-Fi Alliance certification for wireless security.
The update which makes it easier to connect to Wi-Fi hotspots is only applicable to computers that have transitioned to XP SP2.
WPA2 is a product certification that is available through the Wi-Fi Alliance. WPA2 certifies that wireless equipment is compatible with the IEEE 802.11i standard. The WPA2 product certification formally replaces Wired Equivalent Privacy (WEP) and the other security features of the original IEEE 802.11 standard. The goal of WPA2 certification is to support the additional mandatory security features of the IEEE 802.11i standard that are not already included for products that support WPA.
The WPA2/WPS IE Update supports the following features of WPA2, WPA2 Enterprise using IEEE 802.1X authentication and WPA Personal using a preshared key (PSK), Advanced Encryption Standard (AES) using the Counter Mode-Cipher Block Chaining (CBC)-Message Authentication Code (MAC) Protocol (CCMP) that provides data confidentiality, data origin authentication, and data integrity for wireless frames.
It also supports the optional use of Pairwise Master Key (PMK) caching and opportunistic PMK caching. In PMK caching, wireless clients and wireless access points cache the results of 802.1X authentications. Therefore, access is much faster when a wireless client roams back to a wireless access point to which the client already authenticated, optional use of pre-authentication.
