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 WPA protocol implements the Temporal Key Integrity Protocol (TKIP). WEP used a 64-bit or 128-bit encryption key that must be manually entered on wireless access points and devices and does not change.
IEEE 802.11i enhances IEEE 802.11-1999 by providing a Robust Security Network (RSN) with two new protocols: the four-way handshake and the group key handshake. These utilize the authentication services and port access control described in IEEE 802.1X to establish and change the appropriate cryptographic keys.
Wireless security is another aspect of computer security. Organizations may be particularly vulnerable to security breaches [6] caused by rogue access points.. If an employee adds a wireless interface to an unsecured port of a system, they may create a breach in network security that would allow access to confidential materials.

Dynamic WEP refers to the combination of 802.1x technology and the Extensible Authentication Protocol. Dynamic WEP changes WEP keys dynamically. It is a vendor-specific feature provided by several vendors such as 3Com. The dynamic change idea made it into 802.11i as part of TKIP, but not for the WEP protocol itself.
There may be many different key exchange protocols, each with different security properties. However, a common framework is required for agreeing to the format of SA attributes and for negotiating, modifying and deleting SAs. ISAKMP serves as this common framework. ISAKMP can be implemented over any transport protocol.
A prominent application is Wi-Fi Protected Access (WPA), the extended security protocol for wireless networks that addresses the shortcomings of its predecessor, WEP, by frequently replacing session keys through the Temporal Key Integrity Protocol (TKIP), thus defeating some well-known key recovery attacks.
