Protected

Access 2)

consists of AES encryption, pre-authentication and PMKID caching. It provides support for

BSS (Infrastructure) mode and IBSS (ad hoc) mode. WPA and WPA2 are compatible.

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.
