Wi-Fi Alliance Introduces WPA3 Protocol for Increased Security in Wi-Fi Devices

During the CES 2018 earlier this year, Wi-Fi Alliance had announced officially that it would be releasing the WPA3 security protocol for Wi-Fi devices all over the world. Now after months, the consortium of companies which sets up security standards for consumer Wi-Fi products has introduced the WPA3 protocol for authenticating devices on the same network. It is noteworthy that this new update on the Wi-Fi protocol comes 14 years after WPA2 came into existence. However, because of the KRACK (key reinstallation attack) which affected a lot of networks in the past years, the need for a better and more secure protocol was imminent.

Wi-Fi Alliance in its blog post said: “All WPA3 networks use the latest security methods, disallow outdated legacy protocols, and require the use of Protected Management Frames (PMF) to maintain resiliency of mission-critical networks.” Besides this, the consortium has released improvements in terms of WPA3-Personal and WPA3-Enterprise protocols.

The important thing to note about the WPA3-Person is that it offers “more resilient” password-based authentication while using non-complex combinations. Wi-Fi Alliance illustrated that this is done with the help of Simultaneous Authentication of Equals (SAE), a secure key establishment protocol that provides protection against password guessing attempts.

Unlike WPA3 Personal, WPA3-Enterprise facilitates 192-bit security suite for networks transmitting sensitive data. This network protocol would be used by finance and government organisations. The company also remarked that WPA3 would be termed as a requisite for all new Wi-Fi devices over the world, as slowly it will become the standard. Interoperability with WPA2 devices will be maintained while WPA3 is rolled out.
