Wired Equivalent Privacy or Wireless Encryption Protocol (WEP) is a task to protected IEEE 802.11 wireless networks. It is element of the IEEE 802.11 wireless network standard. Because wireless networks broadcast messages using radio, they are susceptible to eavesdrop.
WEP be intended to provide confidentiality comparable to that of a traditional wired lattice. Several serious weakness be identified by cryptanalysts; a WEP nouns can be cracked near around software inside minutes. WEP be superseded by Wi-Fi Protected Access (WPA) within 2003, followed by the full IEEE 802.11i standard (also specified as WPA2) contained by 2004. Despite its weakness, WEP provides a plane of surety that may deter offhand snooping.
WEP is a method to encrypt wireless gridiron signals. It is relatively simple to hack. WPA is more in safe hands and adjectives newer equipment supports WPA. Use WPA where on earth possible.
