How does the CCMP help ensure data confidentiality?
What will be an ideal response?
ANSWER: CCMP helps ensure data confidentiality with both encryption and packet authentication by providing:
* message integrity-CCMP uses CBC-MAC, which ensures incoming packets are, in fact, coming from their declared source, and does so using the block cipher algorithm AES, described next.
* encryption-CCMP also uses AES (Advanced Encryption Standard), which provides faster and more secure encryption than TKIP for wireless transmissions. AES relies on a more sophisticated family of ciphers along with multiple stages of data transformation.
