Which of the following Wi-Fi security protocols uses GCMP-256 for encryption and HMAC-SHA-384 for authentication?CCMPPEAPWEPWPA3

To determine which Wi-Fi security protocol uses GCMP-256 for encryption and HMAC-SHA-384 for authentication, we need to analyze each option:

1. WEP (Wired Equivalent Privacy): An outdated protocol, which uses RC4 for encryption and does not support modern encryption standards like GCMP-256 or authentication methods like HMAC-SHA-384.

2. WPA (Wi-Fi Protected Access): This protocol uses TKIP for encryption and provides improved security over WEP, but still does not utilize GCMP-256 or HMAC-SHA-384.

3. PEAP (Protected Extensible Authentication Protocol): Primarily used for secure transmission of authentication data, PEAP usually does not specify encryption suites like GCMP-256 nor does it specify HMAC-SHA-384 directly in its standard.

4. CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol): While it uses AES for encryption, it does not specify HMAC-SHA-384.

5. WPA3: This latest security protocol indeed supports modern encryption standards. WPA3 utilizes GCMP-256 for encryption and HMAC-SHA-384 for authentication.

Final Answer

The Wi-Fi security protocol that uses GCMP-256 for encryption and HMAC-SHA-384 for authentication is WPA3.
