What is an advantage of using WPA3-Personal instead of WPA2-Personal as a security solution for 802.11 networks?

An advantage of using WPA3-Personal instead of WPA2-Personal as a security solution for 802.11

networks is that WPA3-Personal, also called WPA3-SAE, uses a stronger authentication exchange to

better secure the network. WPA3-Personal uses Simultaneous Authentication of Equals (SAE) as the

key exchange protocol, which provides stronger protection against offline dictionary attacks and

password guessing than WPA2-Personal. SAE uses a Diffie-Hellman key exchange with elliptic curve

cryptography (ECC) to establish a pairwise master key (PMK) between the AP and the client without

revealing it to any eavesdropper. SAE also provides forward secrecy, which means that if one PMK is

compromised, it does not affect the security of other PMKs. WPA2-Personal uses Pre-Shared Key

(PSK) as the key exchange protocol, which is vulnerable to offline brute-force attacks if the

passphrase is weak or leaked. Both WPA3-Personal and WPA2-Personal use AES for encryption, so

there is no difference in that aspect. WPA3-Personal does not use a different encryption algorithm

than WPA2-Personal, but rather a different key exchange protocol. Reference: [CWNP Certified
