Which protocol uses AES-CCMP encryption?

Which protocol uses AES-CCMP encryption?

• A. WEP
• B. WPA
• C. WPA2
• D. WPA3

Answer: (C)

AES-CCMP encryption is what WPA2 uses. CCMP (Counter Mode with CBC-MMAC Protocol) is an AES-based method that provides both confidentiality and integrity for wireless data frames. WPA2 adopted AES-CCMP as the default, replacing the older WEP and the TKIP-based approach used by WPA. WEP relies on a weak RC4-based scheme with poor integrity, and WPA introduced TKIP to improve on WEP but it isn’t as robust as AES-CCMP. WPA3 introduces newer, even stronger methods, but the encryption most commonly associated with WPA2 is AES-CCMP. So the protocol that uses AES-CCMP encryption is WPA2.
