WPA3 Takes Wi-fi Security to the Next Level, Following the Krack Attack

A new announcement has been made in regards of the Wi-Fi Alliance (the organization managing wireless internet technologies): the official release of WPA3 is already a fact:

Wi-Fi Alliance® introduces Wi-Fi CERTIFIED WPA3™, the next generation of Wi-Fi® security, bringing new capabilities to enhance Wi-Fi protections in personal and enterprise networks. Building on the widespread adoption of WPA2™ over more than a decade, WPA3™ adds new features to simplify Wi-Fi security, enable more robust authentication, and deliver increased cryptographic strength for highly sensitive data markets. As the Wi-Fi industry transitions to WPA3 security, WPA2 devices will continue to interoperate and provide recognized security, the statement reads.

WPA3 Comes after the KRACK Vulnerability

In other words, WPA3 is the latest version of Wi-Fi Protected Access otherwise known as WPA – a user authentication technology aimed at wireless connections. The Alliance started developing WPA3 after the discovery of the KRACK vulnerability within the WPA2 protocol. The flaw allowed attackers to gain access to Wi-Fi transmissions guarded by the WPA2 standard.

The Krack attack was capable of exploiting the way the security handshake of the WPA2 encryption protocol is handled. This is a sequence of requests and answers that deliver cryptographically protected data. The researchers uncovered that when the third step is sent using multiple times, in some situations a cryptographic message can be reused in a way which effectively disrupts the security measures.

Currently, WPA3 is optional for brand new device models. However, it is expected to become the ultimate Wi-Fi authentication standard for all Wi-Fi-enabled devices in the years to come. Even though no particular date has been outlined, WPA3 will sustain interoperability with older WPA2 devices so that the transition is flawless.
