What Wi-Fi security protocol uses GCMP-256 for encryption?

WPA
WPA2
WPA3
WEP

The correct answer is: WPA3

WPA3 is the security protocol that employs GCMP-256 for encryption. This protocol is part of the advancements made in wireless security, designed to address vulnerabilities found in its predecessors, WPA and WPA2. GCMP, or Galois/Counter Mode Protocol, provides strong confidentiality and integrity protection for data transmitted over wireless networks. The use of the 256-bit encryption key in GCMP enhances security, particularly against brute-force attacks and provides stronger defenses against various types of cyber threats. WPA3 represents a significant shift towards ensuring secure connections, particularly in environments where sensitive information is transmitted over Wi-Fi. In contrast, other protocols like WPA and WPA2 use different cipher suites that do not include GCMP-256, and WEP, which is an older protocol, is known for its vulnerabilities and use of much weaker encryption methods. Therefore, distinguishing WPA3's implementation of GCMP-256 demonstrates its commitment toward modern security standards in wireless communication.
