WPA is a security technology for wireless networks
that improves on the authentication and encryption features of WEP (Wired
Equivalent Privacy). In fact, WPA was developed by the networking industry in
response to the shortcomings of WEP. One of the key technologies behind WPA is
the Temporal Key Integrity Protocol (TKIP). TKIP addresses the encryption
weaknesses of WEP. Another key component of WPA is built-in authentication that
WEP does not offer. With this feature, WPA provides roughly comparable security to
VPN tunneling with WEP, with the benefit of easier administration and use. This is
similar to 802.1x support and requires a RADIUS server in order to implement. The
Wi-Fi Alliance will call this, 'WPA-Enterprise. ' One variation of WPA is called WPA
Pre Shared Key or WPA-PSK for short - this provides an authentication alternative to
an expensive RADIUS server. WPA-PSK is a simplified but still powerful form of WPA
most suitable for home Wi-Fi networking. To use WPA-PSK, a person sets a static
key or "passphrase" as with WEP. But, using TKIP, WPA-PSK automatically changes
the keys at a preset time interval, making it much more difficult for hackers to find and
exploit them. The Wi-Fi Alliance will call this, 'WPA-Personal.'
