CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol), part of the WPA-PSK2 is an IEEE 802.11i encryption protocol, created to improve upon both WPA-PSK1 (TKIP) and the earlier, insecure WEP protocol. CCM mode (Counter with CBC-MAC) is a mode of operation for cryptographic Block ciphers It is an Authenticated encryption algorithm designed Wi-Fi Protected Access ( WPA and WPA2) is a certification program administered by the Wi-Fi Alliance to indicate compliance with the security protocol created by the IEEE 80211i-2004, or 80211i, is an amendment to the IEEE 80211 standard specifying security mechanisms for wireless networks The amendment has been A security protocol ( cryptographic protocol or encryption protocol) is an abstract or concrete protocol that performs a security -related function Wi-Fi Protected Access ( WPA and WPA2) is a certification program administered by the Wi-Fi Alliance to indicate compliance with the security protocol created by the Temporal Key Integrity Protocol or TKIP is a Security protocol used in the IEEE 802 Wired Equivalent Privacy ( WEP) is a deprecated Algorithm to secure IEEE 802 ^[1]

The CCMP packet

CCMP uses the Advanced Encryption Standard (AES) algorithm. In Cryptography, the Advanced Encryption Standard ( AES) also known as Rijndael, is a Block cipher adopted as an Encryption In Cryptography, the Advanced Encryption Standard ( AES) also known as Rijndael, is a Block cipher adopted as an Encryption In the CCMP, unlike TKIP, key management and message integrity is handled by a single component built around AES. Temporal Key Integrity Protocol or TKIP is a Security protocol used in the IEEE 802 Key management is a term used to describe two different fields (1 Cryptography, and (2 physical key management (or Electronic key management) within building or Data integrity is a term used in Computer science and Telecommunications that can mean ensuring data is "whole" or complete the condition in which data are In Cryptography, the Advanced Encryption Standard ( AES) also known as Rijndael, is a Block cipher adopted as an Encryption

CCMP uses CCMimprove with the following parameters:

• M = 8 - indicating that the MIC is 8 octets,
• L = 2 - indicating that the Length field is 2 octets. CCM mode (Counter with CBC-MAC) is a mode of operation for cryptographic Block ciphers It is an Authenticated encryption algorithm designed
