修订标准-已被取代。 本修正案定义了IEEE 802.11的安全机制，其中包括WEP的定义，以便与原始标准IEEE Std 802.11（1999年版）向后兼容。 该修正案定义了TKIP和CCMP，它们提供了比WEP更强大的数据保护机制。它在IEEE 802.11中引入了安全关联的概念，并定义了称为4路握手和组密钥握手的安全关联管理协议。此外，它还规定了IEEE 802.1X如何被IEEE 802.1X利用。 11个局域网来实现身份验证。

Amendment Standard - Superseded. Security mechanisms for IEEE 802.11 are defined in this amendment, which includes a definition of WEP for backward compatibility with the original standard, IEEE Std 802.11, 1999 Edition. This amendment defines TKIP and CCMP, which provide more robust data protection mechanisms than WEP affords. It introduces the concept of a security association into IEEE 802.11 and defines security association management protocols called the 4-Way Handshake and the Group Key Handshake. Also, it specifies how IEEE 802.1X may be utilized by IEEE 802.11 LANs to effect authentication.
