Temporal Key Integrity Protocol (TKIP)

The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the IEEE

802.11i encryption standard for wireless LANs. TKIP is the next generation of

WEP, the Wired Equivalency Protocol, which is used to secure 802.11 wireless

LANs. TKIP provides per-packet key mixing, a message integrity check and a

re-keying mechanism, thus fixing the flaws of WEP.

Transmission Control Protocol / Internet Protocol (TCP/IP)

TCP/IP is the protocol suite developed by the Advanced Research Projects

Agency (ARPA). It is widely used in corporate Internet works, because of its

superior design for WANs. TCP governs how packet is sequenced for

transmission the network. The term “TCP/IP” is often used generically to refer

to the entire suite of related protocols.

Transmit / Receive

The wireless throughput in Bytes per second averaged over two seconds.

Wi-Fi Alliance

The Wi-Fi Alliance is a nonprofit international association formed in 1999 to certify

interoperability of wireless Local Area Network products based on IEEE 802.11

specification. The goal of the Wi-Fi Alliance’s members is to enhance the user

experience through product interoperability. The organization is formerly known as

WECA.

Wi-Fi Protected Access (WPA)

The Wi-Fi Alliance put together WPA as a data encryption method for 802.11 wireless

LANs. WPA is an industry-supported, pre-standard version of 802.11i utilizing the

Temporal Key Integrity Protocol (TKIP), which fixes the problems of WEP, including

using dynamic keys.

Wide Area Network (WAN)

A WA

N consists of multiple LANs that are tied together via telephone services and /

or fiber optic cabling. WANs may span a city, a state, a country, or even the world.

Wired Equivalent Privacy (WEP)

Now widely recognized as flawed, WEP was a data encryption method used

to protect the transmission between 802.11 wireless clients and

APs. However, it used the same key among all communicating devices. WEP’s

problems are well-known, including an insufficient key length and no automated

method for distributing the keys. WEP can be easily cracked in a couple of hours

with off-the-shelf tools.

Advanced Encryption Standard (AES)

Security issues are a major concern for wireless LANs, AES is the U.S. government’s

next-generation cryptography algorithm, which will replace DES and 3DE
