The security team of Debry Inc. decided to upgrade Wi-Fi security to thwart attacks such as dictionary attacks and key recovery attacks. For this purpose, the security team started implementing…

WEP (Wired Equivalent Privacy) is an outdated and highly insecure protocol susceptible to various attacks, including dictionary and key recovery, and does not use SAE.

WPA (Wi-Fi Protected Access) was an interim standard to address WEP's flaws, introducing TKIP, but it did not utilize SAE and is also vulnerable to attacks.

WPA2 (Wi-Fi Protected Access 2) introduced AES-CCMP and is much stronger than WEP/WPA, but its PSK mode remains susceptible to offline dictionary attacks, which SAE was designed to prevent.

WPA3 (Wi-Fi Protected Access 3) is the latest Wi-Fi security standard and is specifically characterized by its mandatory use of SAE (Simultaneous Authentication of Equals) for stronger authentication and key establishment. SAE, also called Dragonfly Key Exchange, provides enhanced protection against dictionary attacks and significantly improves over WPA2's Pre-Shared Key (PSK) vulnerability to offline brute-force attacks.
