What is TKIP?

TKIP stands for Temporal Key Integrity Protocol. TKIP was introduced to address the shortcomings in WEP encryption. TKIP is also known as WEP key hashing and was initially called WEP2. TKIP is a temporary solution that fixes WEPs key reuse problem. TKIP uses the RC4 algorithm to perform encryption, which is the same as WEP. A major difference from WEP is that TKIP changes the temporal key every packet. The temporal key changes every packet because the hash value for every packet changes.
