Wired Equivalent Privacy (WEP) is a weak 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 26 or 58 hexadecimal digits, is widely in use and is often the first security choice presented to users by router configuration tools.Although its name implies that it is as secure as a wired connection, WEP has been demonstrated to have numerous flaws and has been deprecated in favor of newer standards. In 2003 the Wi-Fi Alliance announced that WEP had been superseded by a higher Wi-Fi standard. In 2004, with the ratification of the full 802.11i standard, the IEEE declared that both WEP-40/64/104/128 "have been deprecated as they fail to meet their security goals".
WPA, refered to as IEEE 802.11i became available in 2003.
