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.
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 ...
CCMP (CTR mode with CBC-MAC Protocol) 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.
MPDU payload is TKIP or CCMP encrypted. MPDU payload and header are TKIP or CCMP integrity protected. Protected frame field of frame control field is set. Only cipher suites already implemented are required. Sender's pairwise temporal key (PTK) protects unicast management frame.
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). The draft standard was ratified on 24 June 2004.

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 authentication using 802.1X.
