Wi-Fi Alliance improves the security of WPA2 and introduces the new WPA3 for this year

Wi-Fi Alliance, a global network of companies that set standards for the Wi-Fi industry. has presented its next WPA3 security protocol. I also announced key improvements in its Wi-Fi security protocol (WPA2), (Wi-Fi Protected Access II), which has existed since 2003.

WPA2 Wi-Fi enhancements provide greater security protection and best practices, while the new WPA3 offers new security capabilities.
The three key Wi-Fi WPA2 protocol enhancements will address the problems of authentication, encryption and configuration.

The first improvement of WPA2 is the use of protected management frameworks (PMF) in Wi Fi devices. The function of protected management frameworks has already been widely adopted in Wi-Fi devices, and is designed to guarantee the integrity of network management traffic in a Wi-Fi network and maintains network resilience, explains Robinson, representative of Wi Fi Alliance

A second enhancement of WPA2 requires companies to perform additional checks on all their Wi-Fi CERTIFIED devices to ensure that they are incorporating best practices in the way they use Wi Fi security protocols and closely related network protocols. For example, Wi Fi tests will evaluate expected behaviors when devices validate network authentication server certificates, says Robinson. This improvement is designed to reduce potential vulnerabilities due to poor configuration of networks or devices.

The third improvement of WPA2, aims to provide greater consistency in the security configuration of the network by standardizing 128-bit level cryptographic suite configurations, similar to those defined for the new 192-bit level.

There are several components - such as information protection (encryption), key establishment, digital signatures and condensed representations of information - that work together as a system to offer solid security. "These improvements will ensure consistency between all the security elements used in a given configuration," he says.

Although the vast majority of Wi Fi devices already meet most of these requirements, the alliance notes that by having them in their Wi-Fi certification program you can be sure that all Wi-Fi CERTIFIED devices will meet this higher level of security protection.

The first ability of WP3 is to protect users who choose weak passwords. Under the WPA3 certification, companies would need to use technology that informs the network every time an attacker guesses a password.

The goal of WPA3 is also to simplify the configuration process and the security of devices with limited visualization interfaces, which are usually associated with IoT or sensor devices. WPA3 certified devices would allow users to connect their smartphone with a sensor device or IoT device, or scan a QR code, and then provision the device on the network.

Improved privacy in open networks is a third standard for WPA3 compatible devices.

"With WPA3, each user of an open network obtains individualized data encryption without the need to configure a network password. The experience is identical to connecting to any open network with the benefit of a higher level of privacy because an attacker can not passively monitor network traffic, "says Robinson.

Finally, WPA3 offered stronger security for government, defense and industrial networks with a new set of protocols that use 192-bit security, or Commercial National Security Algorithm (CNSA) Suite. CNSA, formerly known as Suite B, is designed to support security-sensitive networks, such as those that transmit top-secret information, the Alliance announced.
