The IEEE introduced the WEP as an optional security measure to secure 802 11b Wi Fi WLANs but inherent weaknesses in the standard soon became obvious In response to this situation the Wi Fi Alliance announced a new security architecture in October 2002 that remedies the shortcomings of WEP This standard formerly known as Safe Secure Network SSN is designed to work with existing 802 11 products and offers forward compatibility with 802 111 the new wireless security architecture being defined in the IEEE B 8 Wireless Networking Basics September 2004 Reference Manual for the NETGEAR ProSafe Wireless Access Point 802 11g WG302 WPA offers the following benefits e Enhanced data privacy e Robust key management e Data origin authentication e Data integrity protection 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 will have to support WPA NETGEAR will implement WPA on client and access point products and make this available in the second half of 2003 Existing Wi Fi certified products will have one year to add WPA support or they will lose their Wi Fi certification The 802 111 standard is currently in draft form with ratification due at the end of 2003 While the new IEEE 802 111 standard is being ratified wireless vendors have agreed on WPA as an interoperable interim standard How Does WPA Compare
