802.11i

802.11i is a key element to improving MAC layer security and is applicable
as an alternative to WEP applications. Most manufacturers ship
products without setting any security features. The products come out of
the box unsecure, without encryption, and most users have no idea how
to implement the most basic security measures.
802.11 specifies a portion of the security features that must support
solutions that begin with firmware upgrades that can only be accomplished
using the temporal key integrity protocol (TKIP) in combination
with and advanced encryption standard (AES) (iterated block ciphers)
and TIKP backwards compatibility.
For WLAN products to achieve Wi-Fi certification, they must implement
additional security features above and beyond those already set in
the standard. The constantly evolving corporate networks must integrate
standard forms of encrypted modulation techniques that provide a
greater level of inherent security during wireless transmissions.
