The Wi-Fi Alliance has announced WPA3, a new standard of Wi-Fi security features for users and service providers. This is welcome news, given that a Wi-Fi exploit was uncovered late last year which affected all modern Wi-Fi networks using WPA or WPA2 security encryption, letting attackers eavesdrop on traffic between computers and wireless access points. The new WPA3 features will include “robust protection” when passwords are weak, and will also simplify security configurations for devices that have limited or no display interface.
Obviously good news in light of the problems with WPA2. There are some cool potential features in WPA3, including “individualized data encryption”, which in theory means that different devices on the same network will utilize different encryption schemes—so if somebody compromises a network, they don’t automatically get access to all the other traffic running through it.
Presumably existing devices will be able to reap the benefits of these improvements, but it’s unclear at present. The Wi-Fi Alliance is making some enhancements to WPA2, as well, which hopefully means better security for our many and varied Wi-Fi-enabled devices.
