High Quality Content by WIKIPEDIA articles! IEEE 802.11i-2004 or 802.11i, implemented as WPA2, is an amendment to the original IEEE 802.11. The draft standard was ratified on 24 June 2004. This standard specifies security mechanisms for wireless networks. It replaced the short Authentication and privacy clause of the original standard with a detailed Security clause. In the process it deprecated the broken WEP. The amendment was later incorporated into the published IEEE 802.11-2007 standard.
