Introducing WPA3, the new router and device security standard

WPA2, what is it good for?

Quite a lot, actually.

Since WPA2 was introduced in 2004, it has been the security standard for wireless networks. You may not know about it, but it is built into almost every router available.

WPA2 protects the content transmitted between your wireless device and your router by encrypting wireless connections. By checking passwords match, it prevents devices not on the network from viewing wireless traffic.

Why was a change required?

Following high-profile attacks such as KRACK, WPA2 is due a more secure replacement.

What’s new with WPA3?

PCMag reports that you should only be able to crack a WPA3 network if you are already connected to it.

  • Encryption has been increased to 128-bit
  • Passwords require network interaction to attempt a login – protecting from dictionary hacks
  • More secure public WiFi through encrypting the connection between device and router – even if you don’t have to enter a password to use it
  • Secure connection of screenless IoT devices by using a device such as your smartphone
  • Safer data – if an attacker gets encrypted data but doesn’t learn the password until later, they will not be able to decrypt it
  • WPA3 enterprise offers up to 384-bit encryption

WPA3 will be introduced in late 2018, but widespread adoption is not expected until late 2019.
