IEEE i WPA2

IEEE i (WPA2) IEEE i, is an amendment to the standard specifying security mechanisms for wireless networks. The draft standard was ratified on 24 June 2004, and supersedes the previous WEP, which was shown to have severe security weaknesses.

IEEE i The i architecture contains the following components:  802.1x for authentication (entailing the use of EAP and an authentication server),  RSN for keeping track of associations,  AES-based CCMP to provide confidentiality, integrity and origin authentication.

WPA and IEEE i Wi-Fi Protected Access (WPA) had previously been introduced by the Wi-Fi Alliance as an intermediate solution to WEP insecurities. WPA implemented a subset of i. The Wi-Fi Alliance refers to their approved, interoperable implementation of the full i as WPA2.

Robust Security Network - RSN RSN is an component of i authentication and encryption algorithms to be used for communications between APs and wireless clients. This means that as new threats are discovered, new algorithms can be added.

CCMP CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) is an IEEE i encryption protocol, created to replace, together with TKIP, the insecure WEP protocol.

Devices implementing i Windows Vista  Support WPA2 without any additional patches. Windows XP  Support of WPA2 needs an operating system update and upgrade of wireless adapter drivers.  WPA2 support for Windows XP x64 is included in Windows XP x64 SP2.

Devices implementing i Linux  Support of WPA2 is available. Drivers are needed to support WPA as well as the utility, wpa_supplicant.  A tool called NetworkManager, with GNOME and KDE frontends can be used to configure access to protected wireless networks.

WPA2 WPA2 implements the mandatory elements of i. In particular, in addition to TKIP and the Michael algorithm, it introduces a new AES-based algorithm, CCMP, that is considered fully secure.

WPA2 Official support for WPA2 in Microsoft Windows XP was rolled out on 1 May Note that from March 13, 2006, WPA2 certification is mandatory for all new devices wishing to be Wi-Fi certified.
