If you’ve ever used the wireless in a public place, you know how easy it is to grab information during the initial wireless handshake between the client and the AP. With WPA2, this handshake isn’t secure with open wireless networks. With the advent of WPA3, there is a new option for open networks – OWE, or Opportunistic Wireless Encryption.

Rowell Dionicio takes a quick look at how OWE is going to help with securing the communications between AP and client. He’s got some great packet captures showing how the whole exchange works and how the encryption happens transparently to the client. As Rowell says here:
