A CDE Definition
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).
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.
