WPA-
Enterprise
Wi-Fi Protected Access-Enterprise applies to corporate users. A new
standards-based, interoperable security technology for wireless LAN
(subset of IEEE 802.11i draft standard) that encrypts data sent over radio
waves. WPA is a Wi-Fi standard that was designed to improve upon the
security features of WEP as follows:
Improved data encryption through the temporal key integrity
protocol (TKIP). TKIP uses a hashing algorithm to scramble the
encryption keys and adds an integrity-checking feature to ensure
that the keys have not been tampered with.
User authentication, which is generally missing in WEP, through the
extensible authentication protocol (EAP). WEP regulates access to a
wireless network based on a computer's hardware-specific MAC
address, which is relatively simple to be sniffed out and stolen. EAP
is built on a more secure public-key encryption system to ensure
that only authorized network users can access the network.
WPA is an interim standard that will be replaced with the IEEE's 802.11i
standard upon its completion.
WPA-Personal Wi-Fi Protected Access-Personal provides a level of security in the small
network or home environment.
WPA-PSK (Wi-
Fi Protected
Access-Pre-
Shared Key)
WPA-PSK mode does not use an authentication server. It can be used with
the data encryption types WEP or TKIP. WPA-PSK requires configuration of
a pre-shared key (PSK). You must enter a pass phrase or 64 hex
characters for a pre-shared key of length 256-bits. The data encryption
key is derived from the PSK.
