WEP

Abbreviation for Wired Equivalent
Privacy. An encryption key used in
wireless LAN networks. As an IEEE
standard based on RC4 algorithm
cryptography, WEP is used to secure
IEEE 802.11b wireless networks.
During the transmission of a
message between a wireless LAN
access point and a client device, the
sending side encrypts the data and
the receiving side decrypts it. For
communication to occur, both
devices must use a common code
key, which is called the “WEP key.”
The encryption level is indicated by
the bit count of the key; e.g., 64 bits
or 128 bits. The higher the bit count,
the higher the security level.

WMA

Abbreviation for Windows Media
Audio. WMA is audio compression
technology developed by Microsoft
Corporation that allows audio files to
be compressed to about 1/22 of the
data size of a standard compact disc.

WPA

Abbreviation for Wi-Fi Protected
Access. An encryption standard for
wireless LAN networks created by
the Wi-Fi Alliance to remedy a
number of serious security problems
in the WEP system. In addition to the
network name (SSID) and
encryption key (WEP), this protocol
uses a user authentication framework
called “EAP” (Extensible
Authentication Protocol) and a
protocol called “TKIP” (Temporal
Key Integrity Protocol) which
automatically updates the encryption
code at regular intervals for higher
security.

WPA2

Abbreviation for Wi-Fi Protected
Access 2. An encryption standard for
wireless LAN networks. As an
upgraded version of WPA created by
the Wi-Fi Alliance, this standard
uses AES (Advanced Encryption
Standard) cryptography to provide
stronger security than WPA.

WPS

Abbreviation for Wi-Fi Protected
Setup. A wireless network standard
created by the Wi-Fi Alliance to
allow you to set up a wireless
network easily. A push button
configuration method and a PIN
code method are available.
