The default encryption method defined under the 802.11i amendment. This method uses the Advanced Encryption Standard (AES) cipher. It uses a 128-bit encryption key size and encrypts in 128-bit fixed-length blocks. An 8-byte message integrity check (MIC) is used that is considered much stronger than the one used with Temporal Key Integrity Protocol (TKIP). AES-CCMP is the default encryption method defined by Wi-Fi Protected Access 2 (WPA2).
