IT Security for Collaborative Machines and Human-Machine Interaction

Improved human integration, machine connectivity and decentralized collaborative control systems play an important role in making production systems more flexible.

Cyber-Physical Systems for machine control, mobile HMI or SCADA systems are increasingly connected via Internet-based technologies and must also be protected by this open communication technology.

Based on a STRIDE analysis, the paper presents proposals on how to secure data exchange between CPS as well as between CPS and mobile HMI using IoT communication, whereby the practicability plays an important role.

First results show that the concepts are feasible and are currently undergoing prototypical testing.

Future work will focus on the detailed evaluation with respect to communication performance and the determination of the code overhead of the presented solutions.
