WPA3, the next generation cybersecurity standard for wireless devices, is finally going to see the light of day. This will replace WPA2 which is now around two decades old.
This means that open Wi-Fi security will now be much tougher to pierce. Open Wi-Fi, such as that which is accessible in coffee shops and airports, is quite convenient, however, it is unencrypted. This means that anyone using the same network can intercept the data that is sent through it. WPA3 is all about addressing this problem.
With WPA3, things will be handled differently. Thanks to individualised data encryption, the connection between the router and each device that’s connected to it will be scrambled without having to use any third-party software.
Another component in WPA3 serves as stronger protection against dictionary attacks, so hackers will have a tougher time trying to break in with a simple list of possible passwords. In concrete terms, after a given amount of failed password entry attempts, an attacker will be blocked from making any additional attempts.
A couple of months ago, WPA2 security was fiercely debated, due to an important cybersecurity vulnerability Mathy Vanhoef, a computer security academic, managed to discover.
WPA2 employs a four-way handshake which allows devices with a pre-approved password to connect to a network. WPA3, on the other hand, will use a different type of handshake that is not as vulnerable to dictionary-type password hacks.
WPA3 is scheduled to be introduced later this year.
