The Wi-Fi alliance has officially launched the WPA3 security standard, offering improved password authentication and cryptographic strength.
WPA3 is built on the WPA2 standard and retains interoperability with WPA2-supported devices, while disallowing outdated security protocols.
The standard is currently an optional certification for wireless devices, but will become a requirement as adoption of the improved protocols increases.
WPA3-Personal replaces WPA2’s Pre-Shared Key (PSK) protection with Simultaneous Authentication of Equals (SAE), which is more resistant to offline dictionary attacks and provides more robust password-based authentication.
This allows users to pick passwords which are easier to remember and protects data traffic even if a password is compromised after the data was transmitted.
WPA3-Enterprise includes 192-bit minimum-strength security protocols for increased protection of sensitive data.
The WPA3 security standard will become available on new Wi-Fi Certified devices this year.
