In 2019, researchers disclosed a new side-channel attack called " DragonBlood" that could be used to steal a WPA3 password.Īfter the vulnerability was disclosed, the Hash-to-Element protocol was added to WPA3's Simultaneous Authentication of Equals (SAE) authentication protocol to prevent these types of side-channel attacks. With this release, Microsoft has added support for the WPA3 H2E (Hash-to-Element) protocol, which provides increased protection against side-channel attacks.
