What is WEP?
Wired Equivalent Privacy (WEP) is an easily broken security algorithm for IEEE 802.11 wireless networks. Introduced as part of
the original 802.11 standard ratified in September 1999, its intention was to provide data confidentiality comparable to that of a
traditional wired network. WEP, recognizable by the key of 10 or 26 hexadecimal digits, was at one time widely in use and was
often the first security choice presented to users by router configuration tools.
What is WPA?
Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access II (WPA2) are two security protocols and security certification
programs developed by the Wi-Fi Alliance to secure wireless computer networks. The Alliance defined these in response to
serious weaknesses researchers had found in the previous system, WEP (Wired Equivalent Privacy).
WPA (sometimes referred to as the draft IEEE 802.11i standard) became available in 2003. The Wi-Fi Alliance intended it as an
intermediate measure in anticipation of the availability of the more secure and complex WPA2. WPA2 became available in 2004
and is common shorthand for the full IEEE 802.11i (or IEEE 802.11i-2004) standard.
A flaw in a feature added to Wi-Fi, called Wi-Fi Protected Setup, allows WPA and WPA2 security to be bypassed and effectively
broken in many situations. WPA and WPA2 security implemented without using the Wi-Fi Protected Setup feature are unaffected
by the security vulnerability.
