Abstract
A method for securely transmitting time-critical data within a communication system that includes local networks each having a switch and a plurality of terminals, a controller that controls functions of switches and terminals, and having a control network assigned to the controller and separate from the local networks, where communication within the local networks is implicitly authorized based on an assignment of respective terminals to the same local network, each terminal is assigned a zero trust adapter that captures status information, transfers the status information via the control network to the controller for evaluation and authenticates the terminal to the controller to communication partners, and where the controller determines a trust index for each of the terminals based on the status information and applies rules dependent on the trust index for configuration or permissible communication relationships of the terminals.
