802.11i

abbreviationStandard termTelecom & IT

An IEEE amendment that defines security mechanisms for wireless local area networks.

802.11i is an IEEE standard that introduced robust security network protocols to replace the heavily flawed WEP encryption. It mandates the use of the Advanced Encryption Standard (AES) via the CCMP protocol to ensure data confidentiality and integrity. The standard forms the technical foundation for WPA2, providing strong authentication mechanisms like 802.1X for enterprise environments and pre-shared keys for home networks.
