WEP
Wired Equivalent Privacy
WEP is a security protocol defined in the
IEEE 802.11 standard. It is used to protect wire-
less transmissions in a WLAN against unauthorised access through Encryption of the
data transmitted.
WLAN
Wireless LAN
Wireless LANs enable network components to communicate with a network using radio
waves as the transport medium. A wireless LAN can be connected as an extension to a
wired LAN or it can form the basis for a new network.The basic element of a wireless
network is the cell. This is the area where the wireless communication takes place. A
WLAN can be operated in
Ad-hoc mode or Infrastructure mode .
WLAN is currently specified in Standard IEEE 802.11 . The Gigaset SX541 WLAN dsl com-
plies with Standard 802.11g.
WPA
WPA was developed to improve the security provided by
WEP . WPA uses complex proce-
dures to generate keys, such as TKIP (Temporal Key Integrity Protocol). In addition, WPA
can use an authentication server (for example a RADIUS server) to increase security.
WPA-PSK
WPA Pre-shared Key
Variant of
WPA data encryption, in which new keys are automatically generated at reg-
ular intervals by means of a keyword (Pre-shared Key). The key is updated after defined
periods (
Rekey Interval ).
