Temporal Key Integrity Protocol (TKIP)

The Temporal Key Integrity Protocol (TKIP) is a security mechanism for the Institute of Electrical and Electronics Engineers IEEE that provides a more robust data protection than Wired Equivalent Privacy (WEP) . [1]. TKIP is a RC4 stream encryption protocol for wireless LANs (WLANs). TKIP is the encryption method used in Wi-Fi Protected Access (WPA), it includes a group of algorithms like the original WEP with an additional code at the beginning and at the end that "wraps" and modifies the original WEP programming. It actually includes four additional algorithms for increased security: a cryptographic message integrity check, an initialization-vector sequencing mechanism, a per-packet key-mixing function and a re-keying mechanism.
