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 Superseded by WPA and 802.11i but still in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.
