Question

Which WPA3 mode uses SHA-256 for authentication and key management?

Options

ASAE
B802.1x
COWE
Dtransition

Why each option

WPA3 employs Simultaneous Authentication of Equals (SAE) as its robust key exchange mechanism for WPA3-Personal, which leverages SHA-256 for secure authentication and key management.

ASAE

B802.1x

802.1X is an authentication framework typically used in WPA2/WPA3-Enterprise, but it is not a WPA3 mode itself and does not define the hashing algorithm for key management in the way SAE does for WPA3-Personal.

COWE

Opportunistic Wireless Encryption (OWE) is a WPA3 mode (Wi-Fi Enhanced Open) designed for enhanced open Wi-Fi networks that encrypts traffic without authentication, but it does not use SHA-256 for authentication and key management in the same manner as SAE.

Dtransition

WPA3 transition mode allows a network to concurrently support both WPA2 and WPA3 clients, serving as a deployment strategy rather than an authentication or key management protocol that specifically uses SHA-256.
