What is WPA3
Every generation of computer technology spawns both new promise and new problems. When the first universities allowed users to connect to powerful mainframes, unruly students found ways of accessing other student’s information to play pranks on each other, requiring the creation of password protection and access rights.
Today, computers and wireless networks occupy every aspect of life, from schools, hospitals, businesses, libraries - even coffee shops and buses offer WiFi access. But with all this access, there is the need for WiFi security. A person connecting via their laptop could be transmitting the passwords to their bank account over the air for a hacker to pick up.
The biggest problem with allowing access to a local WiFi network isn’t just WiFi encryption, but how to register devices onto the WiFi network. If there’s a shared password, then anyone who shares that with another person or writes it down runs the risk of unauthorized users getting access to the network. For those old enough, remember that scene from the movie “Wargames” where Matthew Broderick’s character would purposely get detention so he could find the network’s password written down in a secretary’s desk? Hackers use the same technique when someone writes down the WiFi password on a Post-It on their desk to get access into the network and start capturing packets.
WPA3 security is designed to help prevent that. Rather than relying on shared passwords, WPA3 signs up new devices through processes that don’t require the use of a shared password. This new system, called Wi-Fi Device Provisioning Protocol (DPP), works by transmitting how to gain access to the system without transmitting a password into the air. With DPP, users use QR codes or NFC tags to let devices onto the network. By snapping a picture or receiving a radio signal from the router, a device can be authenticated to the network without sacrificing security.
