    The Wi-Fi Alliance is now performing interoperability certification testing on Wi-Fi Protected Access products. Starting August of 2003, all new Wi-Fi certified products have to support WPA. NETGEAR is implementing WPA and WPA2 on client and access point products. The 802.11i standard was ratified in 2004.

    Reference Manual for the NETGEAR ProSafe 802.11g Wireless Access Point WG102 How Does WPA Compare to WPA2 (IEEE 802.11i)? WPA is forward compatible with the WPA2 security specification. WPA is a subset of WPA2 and used certain pieces of the early 802.11i draft, such as 802.1x and TKIP. The main pieces of WPA2 that are not included in WPA are secure IBSS (Ad-Hoc mode), secure fast handoff (for specialized 802.11 VoIP phones), as well as enhanced encryption protocols, such as AES-CCMP.
  • Page 95 Reference Manual for the NETGEAR ProSafe 802.11g Wireless Access Point WG102 The primary information conveyed in the Beacon frames is the authentication method and the cipher suite. Possible authentication methods include 802.1X and Pre-shared key. Pre-shared key is an authentication method that uses a statically configured pass phrase on both the stations and the access point.
  • Page 96: Wpa/Wpa2 Authentication: Enterprise-Level User Authentication Via 802.1X/Eap And Radius

    WPA supports Extensible Authentication Protocol (EAP). For environments without a RADIUS infrastructure, WPA supports the use of a pre-shared key. Together, these technologies provide a framework for strong user authentication. Windows XP implements 802.1x natively, and several NETGEAR switch and wireless access point products support 802.1x.
