W
Wired Equivalent Privacy (WEP)—A security protocol used in 802.11 wireless
networking, WEP is designed to provide security equivalent to that found in regular
wired networks. This is achieved by using basic symmetric encryption to protect
data sent over wireless connections, so that sniffing or wireless transmissions does
not produce readable data and so drive-by attackers cannot access a wireless LAN
without additional efforts and attacks.
WPA—Protocol enhancing the service and security offering delivered in WEP and
basic 802.11. Includes support for TKIP and MIC encryption, a median step to
supporting a true cryptographic algorithm such as AES.
WPA2 (or 802.11i)—Recently ratified protocol enhancing the service and security
offering delivered in WEP and 802.11. Includes support for 128bit AES encryption
and support for access point pre-authentication fast roaming capability.
WLAN—Wireless Local Area Network.
Wireless Transport Layer Security (WTLS)—A security level for applications based
on the Wireless Application Protocol (WAP). WTLS is based on transport layer
security (TLS) but has been modified to work with the low-bandwidth, high latency,
and limited-processing capabilities found in many wireless networking
implementations.
X
X.509 digital certificate—A digital certificate that uniquely identifies a potential
communications party or participant. An X.509 certificate includes a party’s name
and public key, but it can also include organizations affiliation, service or access
restriction, and a host of other access and security related information.
