What do you think about Robot Communication security

Hello Everyone, When one robot completes its task and then passes on the information to the other robot preferably installed on a different server/network . what is the security for communication. Its it using HTTP or any other file-sharing protocol, and if HTTP is used, is there a way to secure it via HTTPS. If yes do robots also have a configuration to store their SSL certificate, I understand that a robot when communicates to Orchestrator, the orchestrator has the provision to install an SSL certificate so that the robot or any user can authenticate. For a robot to Robot to communicate in HTTPS, do robots also have a similar SSL certificate config setup?
Thanks in Advance
