Wireless Security Terms

The Advanced Features of the NP644 include the ability to select from several types of Wireless Security.

WEP

WEP stands for Wired Equivalent Privacy. Introduced with

 

802.11b, WEP uses encryption to protect data confidentiality

 

by way of pre-shared keys (passwords or pass-phrases) that are

 

entered at both ends. Superseded by WPA and 802.11i but still in

 

use.

WPA

WPA stands for Wi-Fi Protected Access - authorizes and

 

identifies users based on a secret key that changes automatically

 

at a pre-defined interval. This is called TKIP (Temporal Key

 

Integrity Protocol) to change the temporal key every 10,000

 

packets (= unit of data.) Keys can either be pre-shared or

 

established by a RADIUS Server.

RADIUS

RADIUS is part of 802.11i security; this is a wireless standard

 

which is only concerned with wireless security standards.

 

Authentication is based around a secure server with a challenge-

 

and-response method of interaction which verifies the identity

 

of the client wishing to connect to the network. If you wish to

 

connect to a RADIUS server ask the Network Administrator for

 

details. RADIUS servers are not usually used as part of home

 

networks.
