clients and access points. Then it combines the temporal key with
the client's MAC address and adds a 16-octet initialization vector
to create the key that will encrypt the data. This procedure
ensures that each station uses different key streams to encrypt
the data.
TCP/IP - Transmission Control Protocol/Internet Protocol. This is
the standard protocol for data transmission over the Internet.
TCP - Transmission Control Protocol - TCP and UDP (User
Datagram Protocol) are the two transport protocols in TCP/IP.
TCP ensures that a message is sent accurately and in its entirety.
However, for real-time voice and video, there is really no time or
reason to correct errors, and UDP is used instead.
UDP - User Datagram Protocol - A protocol within the TCP/IP
protocol suite that is used in place of TCP when a reliable
delivery is not required. For example, UDP is used for real-time
audio and video traffic where lost packets are simply ignored,
because there is no time to retransmit. If UDP is used and a
reliable delivery is required, packet sequence checking and error
notification must be written into the applications.
Wi-Fi Protected Access (WPA) – Wi-Fi Protected Access (WPA)
is a set of interoperable security improvements that greatly
increase the level of data encryption and authentication for
existing and future wireless LAN systems. It solves several issues
with the widely used WEP standard.
Wired Equivalent Privacy (WEP) - “Wired Equivalent Privacy” is
based on the use of 64-bit or 128-bit keys and the popular RC4
encryption algorithm. Wireless devices without a valid WEP key
will be excluded from network traffic.
