WiFi Alliance introduced WiFi Certified WPA3 to replace current WPA2 security standard

WiFi Alliance has just introduced WiFi CERTIFIED WPA3 (Wi-Fi Protected Access version 3) as the next generation WiFi security standard, bringing new capabilities to enhance WiFi protections in both personal and enterprise wireless networks.

Key capabilities of WPA3 include:
  • WPA3-Personal: more resilient, password-based authentication even when users choose passwords that is simple to remember. WPA3 will leverage on Simultaneous Authentication of Equals (SAE), which is a secure key establishment protocol between devices, to provide stronger protections for users against password guessing attempts by third parties.
  • WPA3-Enterprise: offers the equivalent of 192-bit cryptographic strength, providing additional protections for networks transmitting sensitive data, such as government or finance. The 192-bit security suite ensures a consistent combination of cryptographic tools are deployed across WPA3 networks.
With the evolution of WiFi security from current WPA2 to WPA3, we can expect:
  • WiFi password to be a lot more difficult to crack.
  • WiFi CERTIFIED Easy Connect - IoT devices can connect to WiFi network more easily.
  • WiFi data sniffed and recorded without knowing your password will not be able to decrypt even if your password is obtained later.
  • WiFi CERTIFIED Enhanced Open - communication in open connection (WiFi connection without the need of any password) will also be encrypted, therefore much more secured than WPA2 open connection. In current WPA2, if the WiFi is connected using open connection without the need of password, the communication between the WiFi connected device and access point is not encrypted.
  • Stronger WiFi encryption by replacing the existing PSK (Pre-Shared Key) system in WPA2 with the new SAE system.
Anyhow, in order to enjoy the benefits of using WiFi WPA3, both the access point (or wireless router) and the connecting device must support this new WiFi security standard. Devices that support WPA3 will probably hitting the market from year 2019 onwards and gradually replacing the existing which only support up to WPA2.
