Wi-Fi Protected Access 2 (WPA2) implements the 802.11i standard. The standard's mandatory encryption suite is CCMP, which uses the Advanced Encryption Standard (AES). TKIP was retained only for backward compatibility and was officially deprecated because multiple practical attacks can recover or inject packets. Therefore, selecting WPA2-AES/CCMP (often shown simply as "WPA2-AES") gives the strongest protection among the listed choices, whereas any option that uses TKIP-or the legacy WEP algorithm-offers significantly weaker security.
