The main feature of WPA3 (Wi-Fi Protected Access 3) is to enhance the security of wireless networks. Among the options provided:
a. Simultaneous authentication of equals (SAE) is a key feature of WPA3, providing a more secure method of authentication for devices connecting to the network.
b. RC4 stream cipher with TKIP (Temporal Key Integrity Protocol) is not a feature of WPA3. In fact, WPA3 was designed to move away from RC4 and TKIP, which were used in earlier security protocols like WPA and WPA2 due to security vulnerabilities.
c. Management protection frames are a part of WPA3 and enhance security by protecting management frames from tampering.
d. Enhanced Open is another feature of WPA3, designed to enhance the security of open networks.
So, the correct answer is:
b. RC4 stream cipher with TKIP
