IEEE 802.11i
IEEE 802.11i is an extension of the IEEE 802.11 standard for wireless LAN (wireless data networks) to include security protocols
- Temporal Key Integrity Protocol (TKIP) and
- CTR with CBC-MAC Protocol (CCMP).
These are summarized under the umbrella term Robust Security Network Association (RSNA). The aim of the expansion was to decisively improve the previously holey encryption method Wired Equivalent Privacy (WEP).
Part of the protocol was published before completion under the name WPA . WPA allows more secure encryption through the use of the Temporal Key Integrity Protocol ( TKIP ). The use of “pre-shared keys” made integration into existing systems easier. The full extension is implemented by WPA2 .
The use of IEEE 802.1X based on the RADIUS protocol allows users to be clearly identified. In addition, 802.11i includes the rules for using the Advanced Encryption Standard (AES) to encrypt data.
IEEE 802.11i was specified in 2004 and later merged into the IEEE 802.11-2007 standard .
Standards according to IEEE:
- IEEE 802.11i / D3.0 is WPA (WPA-Personal and WPA-Enterprise). It is announced in the beacons as WPA IE.
- IEEE 802.11i / D9.0 is WPA2 (WPA2-Personal and WPA2-Enterprise). It is announced in the beacons as RSN IE.
