WPA3 uses which encryption for the key exchange?
What is SAE replacing the PSK four-way handshake with Simultaneous Authentication of Equals (SAE), a version of the Internet Engineering Task Force's dragonfly handshake in which either the client or AP can initiate contact. Each device then transmits its authentication credentials in a discrete, one-off message, instead of in a give-and-take, multipart conversation. Importantly, SAE also eliminates the reuse of encryption keys, requiring a new code with every interaction. Without open-ended communication between AP and client or encryption key reuse, cybercriminals can't as easily eavesdrop or insert themselves into an exchange.
