An IEEE standard security protocol for 802.11 wireless networks that was developed to replace the original WEP protocol. Also known as "Robust Security Network" (RSN), 802.11i provides sophisticated authentication using a variety of protocols (802.1X, EAP and RADIUS) and strong security with the AES-CCMP encryption protocol. However, in order to allow in-place upgrading of older WEP hardware, 802.11i also supports the TKIP protocol, which is less robust than AES-CCMP, but far superior to WEP (see WPA for more details).
Wi-Fi Certification
The Wi-Fi Alliance provides certification for 802.11i-compliant products with its Wi-Fi Protected Alliance (WPA) logo program. The WPA and WPA2 logos certify compliance with a subset of 802.11i or the full 802.11i protocol. See WPA.
