802.11i is a standard for wireless local area networks (WLANs) that provides
improved encryption
for networks that use the popular 802.11a, 802.11b (which includes Wi-Fi) and 802.11g standards. The
802.11i standard requires new encryption key
protocols, known as Temporal Key Integrity Protocol (TKIP) and Advanced
Encryption Standard (AES). The
802.11i standard was officially ratified by the IEEE in June of 2004,
and thereby became part of the 802.11 family of wireless
network specifications.
The 802.11i specification offers a level of security sufficient to satisfy most government
agencies. However, AES requires a dedicated chip, and this may mean hardware upgrades for most
existing Wi-Fi networks. Other features of 802.11i are key caching, which facilitates fast
reconnection to the server for users who have temporarily gone offline, and pre-authentication,
which allows fast roaming and is
ideal for use with advanced applications such as Voice over Internet Protocol (VoIP).
