Which cryptographic protocol in WPA3 offers authenticated encryption with 128-bit and 192-bit AES options?

The correct response highlights GCMP (Galois Counter Mode Protocol) as the cryptographic protocol in WPA3 that provides authenticated encryption with both 128-bit and 192-bit AES options. GCMP is designed to improve security and performance in wireless communications by leveraging the characteristics of the Galois field to ensure both confidentiality and integrity of the data being transmitted.

GCMP operates using the Galois Counter Mode of operation, which allows for efficient encryption and decryption processes by enabling parallel processing of encryption operations. This results in faster encryption while maintaining strong security standards. The inclusion of both 128-bit and 192-bit options provides flexibility for different security requirements, thus allowing users to adjust encryption strength based on their specific needs.

While other cryptographic methods such as CCMP are notable in previous security protocols like WPA2, they do not offer the same level of flexibility and modern enhancements found in GCMP. SAE is focused on secure key establishment and does not directly handle data encryption, and protection frames are more about the delivery mechanism for ensuring data integrity rather than the encryption process itself.
