Wi-Fi Protected Access 2 (WPA2)

Explanation:

The Wi-Fi Protected Access 2 (WPA2) makes some alterations to the encryption algorithm that were used in WPA and WEP to what is known as the  Advanced Encryption Standard (AES). This is a 128-bit block cipher considered to be much more difficult to crack than the usual 128-bit TKIP wrapper. However, although WPA2 offers a much more tougher encryption standard, it is important to note that it is not hack proof.
