Which protocol is part of WPA3 for maintaining confidentiality and integrity?

CCMP
GTK
GCMP
TKIP

The correct answer is: GCMP

The correct answer highlights GCMP (Galois/Counter Mode Protocol) as part of WPA3 for maintaining confidentiality and integrity. GCMP is a modern encryption mode that uses Galois field multiplication to provide authenticated encryption with associated data. This method ensures that both the confidentiality of the data and its integrity are preserved during transmission, making it a robust choice for securing wireless communications. In the context of WPA3, which is an improvement over its predecessors, the use of GCMP reflects a shift towards enhanced security features. This mode not only increases resistance to attacks but also supports the performance requirements of modern networks. Other options, while relevant in the context of wireless security, do not align with the specific advancements introduced in WPA3. For example, CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) was primarily used in WPA2 and does not incorporate the updated mechanisms found in WPA3. GTK (Group Temporal Key) and TKIP (Temporal Key Integrity Protocol) are also part of the legacy security features from previous standards and do not provide the same level of security enhancements targeted by WPA3.
