WPA2
Wi-Fi Protected Access 2 (WPA2). This is the second generation of
WPA that complies with the IEEE TGi specification. WPA2 consists
of AES encryption, pre-authentication and PMKID caching. It
provides support for BSS (Infrastructure) mode and IBSS (ad hoc)
mode. (Not compatible with WPA.)
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 scrambles the keys using a
hashing algorithm and, by adding an integrity-checking
feature, ensures 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.
