Windows XP download boosts 802.11 security.
Microsoft released Monday (March 31) for download a free patch that adds Wi-Fi Protected Access (WPA) to both consumer and business versions of its Windows XP operating system. WPA offers an interim boost in security for 802.11 networks while the 802.11i standards effort continues its work.
WPA uses two 128-bit keys for authentication and those keys can be dynamically generated. Existing 802.11 security only uses one static key. [Hack the Planet]
