Question

How does WPA3 improve security?

Options

AIt uses SAE for authentication.
BIt uses RC4 for encryption.
CIt uses TKIP for encryption.
DIt uses a 4-way handshake for authentication.

Explanation

WPA3 improves Wi-Fi security by replacing the older Pre-Shared Key (PSK) exchange with Simultaneous Authentication of Equals (SAE) for stronger authentication.

Common mistakes.

B. RC4 is a weak stream cipher that was used in older, less secure protocols like WEP and is not part of WPA3.
C. TKIP (Temporal Key Integrity Protocol) was used in WPA and WPA2 as an interim solution to improve WEP, but it is considered insecure and is not used in WPA3.
D. The 4-way handshake is used in WPA and WPA2 for deriving session keys after initial authentication, but WPA3's improvement focuses on the authentication method itself (SAE) to prevent dictionary attacks during the initial key exchange.
