integrity check and a re-keying mechanism, thus fixing the flaws
of WEP.
WAN
A wide area network (WAN) is a geographically dispersed
telecommunications network. The term distinguishes a broader
telecommunication structure from a local area network. A wide
area network may be privately owned or rented, but the term
usually connotes the inclusion of public (shared user) networks.
An intermediate form of network in terms of geography is a
metropolitan area network .
WEP
WEP (Wired Equivalent Privacy) is 802.11’s optional encryp-
tion standard implemented in the MAC layer that most radio
network interface card (NIC) and access point vendors support.
Basic wireless security provided by Wi-Fi. In some instances,
WEP may be all a home or small-business user needs to protect
wireless data. WEP is available in 40-bit (also called 64-bit), or in
108-bit (also called 128-bit) encryption modes. As 108-bit en-
cryption provides a longer algorithm that takes longer to decode,
it can provide better security than basic 40-bit (64-bit) encryption.
Wi-Fi
An interoperability certification for wireless local area net-
work (LAN) products based on the Institute of Electrical and
Electronics Engineers (IEEE) 802.11 standard.
WLAN
Also referred to as LAN. A type of local-area network that uses
high-frequency radio waves rather than wires to communicate
between nodes.
