What is the encryption used by WPA3?

WPA3 primarily utilizes the Simultaneous Authentication of Equals (SAE) for its authentication process, which involves the use of elliptic curve cryptography. Specifically, the Elliptic Curve Diffie-Hellman (ECDH) algorithm is employed to facilitate secure key exchange between devices on a wireless network. This enhances the security of the authentication process by resisting offline dictionary attacks that were more prevalent in earlier versions like WPA2.

The inclusion of elliptic curve cryptography in WPA3 greatly improves the overall security posture of wireless networks by providing stronger encryption methods directly tied to secure key management practices, essential for protecting users' data in increasingly sophisticated threat landscapes. This focus on modern cryptography is a significant advancement in securing wireless communications compared to earlier protocols.
