The protocol used by WPA2, based on the Advanced Encryption Standard (AES) cipher along with strong message authenticity and integrity checking is significantly stronger in protection for both privacy and integrity than the RC4-based TKIP that is used by WPA. Among informal names are AES and AES-CCMP.
Temporal Key Integrity Protocol (TKIP / t iː ˈ k ɪ p /) is a security protocol used in the IEEE 802.11 wireless networking standard. TKIP was designed by the IEEE 802.11i task group and the Wi-Fi Alliance as an interim solution to replace WEP without requiring the replacement of legacy hardware.
WPA implemented a subset of a draft of 802.11i. The Wi-Fi Alliance refers to their approved, interoperable implementation of the full 802.11i as WPA2, also called RSN (Robust Security Network). 802.11i makes use of the Advanced Encryption Standard (AES) block cipher, whereas WEP and WPA use the RC4 stream cipher.

The TKIP encryption algorithm was developed for WPA to provide improvements to WEP that could be fielded as firmware upgrades to existing 802.11 devices. The WPA profile also provides optional support for the AES-CCMP algorithm that is the preferred algorithm in 802.11i and WPA2. WPA Enterprise provides RADIUS based
CCMP is based on AES processing and uses a 128-bit key and a 128-bit block size. CCMP uses CCM with the following two parameters: M = 8; indicating that the MIC is 8 octets (eight bytes). L = 2; indicating that the Length field is 2 octets. A CCMP Medium Access Control Protocol Data Unit (MPDU) comprises five sections. The first is the MAC ...
Only TKIP/AES frames are protected and WEP/open frames are not protected. The following management frames can be protected: Disassociate; Deauthenticate; Action Frames: Block ACK Request/Response (AddBA), QoS Admission Control, Radio Measurement, Spectrum Management, Fast BSS Transition; Channel Switch Announcement directed to a client (Unicast)

Wi-Fi Protected Access (WPA) better than WEP, a 'pre-standard' partial version of 802.11i 802.11i a.k.a. WPA2, uses AES and other improvements on WEP A5/1 and A5/2 cell phone encryption for GSM
