Which open standard defines the combination of Extensible Authentication Protocol with Advanced Encryption Standard for providing strong wireless LAN client security?

The full standard IEEE 802.11i (also known as WPA2 or RSN)) is designed to provide secured communication of wireless LAN as defined by all the IEEE 802.11 specifications. IEEE 802.11i enhances the WEP (Wireline Equivalent Privacy), a technologies used for many years for the WLAN security, in the areas of encryption, authentication and key management. IEEE 802.11i is based on the Wi-Fi Protected Access (WPA), which is a quick fix of the WEB weaknesses.

The aim of 802.11i was to produce a specification for a robust security network (RSN) designed to enhance:
* Authentication
* Key management
* Confidentiality and integrity

The IEEE 802.11i has the following key components:

1. Temporal Key Integrity Protocol (TKIP): session key establishment and re-negotiation
2. Counter-Mode/CBC-MAC Protocol (CCMP): an AES-based protocol to provide confidentiality, integrity and origin authentication
3. IEEE 802.1x for authentication (entailing the use of EAP and an authentication server)

Advanced Encryption Standard (AES) is the cipher system used by WPA2. It is the equivalent of the RC4 algorithm used by WPA. However the encryption mechanism is much more complex and does not suffer from the problems associated with WEP. AES is a block cipher, operating on blocks of data 128bits long.

Note: WPA only implemented a subset of a draft of 802.11i. It is not the full standard of IEEE 802.11i.

IEEE 802.11i-2004, or 802.11i for short, is an amendment to the original IEEE 802.11, implemented as Wi-Fi Protected Access II (WPA2).
