If they want security, then why not just use WPA2 encryption [with certificates]?

For example, for general use at driver training, demonstrations, and possibly off-season events, either a public certificate can be used or they can just operate the robots over an unencrypted network. But at every event, a unique and time-sensitive certificate is loaded onto the controllers for WPA2 authentication.

After the competition, the time-sensitive certificate deactivates, and the team can return to using the robot on unencrypted networks.
