TKIP employs a per-packet key, meaning that it dynamically generates a new 128-bit key for each packet and thus prevents the types of attacks that compromised WEP. [ 4 ] WPA also includes a Message Integrity Check , which is designed to prevent an attacker from altering and resending data packets.
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.
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
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.

WPA is based on the Temporal Key Integrity Protocol (TKIP), which was designed to allow migration from WEP to WPA on the equipment already deployed. The major improvements in security are the dynamic encryption keys. For small networks, the WPA uses a "pre-shared key" which is based on a shared key. Encryption can be vulnerable if the length of ...
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)
For example, a replacement for WEP, Wi-Fi Protected Access (WPA), uses three levels of keys: master key, working key and RC4 key. The master WPA key is shared with each client and access point and is used in a protocol called Temporal Key Integrity Protocol (TKIP) to create new working keys frequently enough to thwart known attack methods. The ...
