Robot to Robot Communication security

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

Where do you see robot to robot communication? There is nothing inherently done by UiPath in this regard, so if you are having two robots communicate to each other it is done programmatically via workflows. Protocols used are whatever you design.
