Wi-Fi Protected Access (WPA) is another encryption standard designed for the IEEE 802.11 network and is the successor of the WEP standard. WPA utilizes the Temporal Key Integrity Protocol (TKIP), which uses the RC4 cipher (128-bit per packet) for data encryption (confidentiality). TKIP, however, mitigated the vulnerabilities from WEP by simply increasing the size of initialization vectors (IVs) and mixing their functions. The 128-bit Temporal Key is combined with the client device's media access control (MAC) address and the IVs to create a keystream that is then used for data encryption.
