Overview Over the past year, many Wi-Fi Alliance members and their customers have become increasingly concerned about the vulnerabilities of Wired Equivalent Privacy (WEP), the basic mechanism to date for interoperable security in Wi-Fi certified products. In response, the Wi-Fi Alliance in conjunction with the IEEE, has driven an effort to bring strongly enhanced, interoperable Wi-Fi security to market in the first quarter of 2003. The result of this effort is Wi-Fi Protected Access (WPA).

Wi-Fi Protected Access is a specification of standards-based, interoperable security enhancements that strongly increase the level of data protection and access control for existing and future wireless LAN systems. Designed to run on existing hardware as a software upgrade, Wi-Fi Protected Access is derived from and will be forwardcompatible with the upcoming IEEE 802.11i standard. When properly installed, it will provide wireless LAN users with a high level of assurance that their data will remain protected and that only authorized network users can access the network.
