Correct answer: WPA3, WPA2.
Why this is the answer
WPA2 and WPA3 are the two wireless security standards that utilize Counter Mode CBC-MAC Protocol (CCMP) for robust encryption and integrity. CCMP, based on AES (Advanced Encryption Standard), provides strong data confidentiality and authentication, making WPA2 and WPA3 significantly more secure than their predecessors. WPA2 introduced CCMP as its primary encryption mechanism, replacing the weaker TKIP used in WPA. WPA3 builds upon WPA2's security by mandating CCMP and introducing additional features like Simultaneous Authentication of Equals (SAE) for enhanced key exchange. WEP is an outdated standard with known vulnerabilities, using RC4 encryption. WPA, the predecessor to WPA2, primarily used TKIP, which is also considered insecure. Wi-Fi 6 is a Wi-Fi generation standard, not a security protocol itself, and it leverages WPA3 for security.
