IEEE 802.11i-2004
IEEE 802.11i extends the IEEE 802.11 standard for wireless LAN ( wireless data networks ) to ensure the safety protocols
- Temporal Key Integrity Protocol ( TKIP) and
- CTR with CBC-MAC Protocol ( CCMP ).
These are summarized under the term Robust Secure Network Association ( RSNA). IEEE 802.11i has risen in the IEEE 802.11-2007.
The extension of the IEEE 802.11 standards will significantly improve the previously holey encryption methods: Wired Equivalent Privacy ( WEP).
A part of the protocol was anticipated under the name WPA before completion. WPA allows a more secure encryption by using Temporal Key Integrity Protocol ( TKIP). Through the use of "pre -shared keys " to integrate into existing systems has become easier. The full extension is implemented by WPA2.
The use of IEEE 802.1X -based RADIUS allows the unique identification of users. In addition, 802.11i provides rules for the use of Advanced Encryption Standard (AES ) to encrypt data.
According to IEEE standards:
- IEEE 802.11i/D3.0 is WPA ( WPA-Personal and WPA- Enterprise). It is advertised in the beacons as WPA IE.
- IEEE 802.11i/D9.0 is WPA2 ( WPA2- Personal and WPA2 - Enterprise). It is advertised in the beacons as RSN IE.
