CCMP
 CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) is an IEEE 802.11i encryption protocol, created to replace WEP, an earlier, insecure protocol. CCMP uses the Advanced Encryption Standard (AES) algorithm. In the 802.11i standard, unlike WPA, key management and message integrity is handled by a single component CCMP built around AES.
The CCMP packet
The process of encrypting data is done through encapsulation. The encapsulation process is completed through encryption and the packet headers being wrapped for transmission. The CCMP encapsulations attempt to ensure the confidentiality and integrity of the communications channel, and to prevent replay attacks. Integrity is assured by calculating a MIC (Message Integrity Code) sum to check if a message is altered, protecting data from reply attacks. In this case, CCMP uses the AES algorithm from TKIP. |
