Estándar para asegurar redes inalámbricas 802.11. También se conoce como
WPA2 y sustituye al WEP original.
IEEE 802.11i, also known as
WPA2, is an amendment to the 802.11 standard specifying security mechanisms for
wireless networks (see Wi-Fi). The draft standard was ratified on 24 June 2004,
and supersedes the previous security specification, Wired Equivalent Privacy
(WEP), which was shown to have severe security weaknesses. Wi-Fi Protected
Access (WPA) had previously been introduced by the Wi-Fi Alliance as an
intermediate solution to WEP insecurities. WPA implemented a subset of 802.11i.
The Wi-Fi Alliance refers to their approved, interoperable implementation of
the full 802.11i as WPA2. 802.11i makes use of the Advanced Encryption Standard
(AES) block cipher; WEP and WPA use the RC4 stream cipher.
