Integration Approach for Communications-based Train Control Applications in a High Assurance Security Architecture

Schulz, Thorsten; Golatowski, Frank; Timmermann, Dirk

The secure integration of model-based, safety-critical applications implemented in the programming suite Ansys SCADE is explained with the help of a demonstrator. The interoperability between the embedded devices of the demonstrator is achieved using the new TRDP middleware. Remote connections are secured using the WireGuard secure network channel. The demonstrator security concept addresses the different life cycles of its heterogeneous components by adoption of the robust MILS separation architecture. The goal of this open demonstrator is to show how these essential technologies can be composed to a secure safety-critical system.
