Certification Cycles of Train Cyber Gateway

Prochazka, Jan; Novobilsky, Petr; Prochazkova, Dana; Kertis, Tomas

The Critical Infrastructure Protection (CIP) is a classic example of system of systems (SoS) management. We pay special attention to interdependencies among systems within SoS. The article deals with the requirements for the cyber gateway at the train transportation management system. More and more telemetry and remote control through communication systems are used on the track because of the technological development. The train at cyberspace acts as an end network that is connected to the operating center network via an open public network. The gateway must then meet the requirements of the railway infrastructure as well as the cyber infrastructure.

We deal with the integration of various requirements for the train gateway into one verification and certification cycle in this paper. The requirement integration is important because, in the first it is necessary to ensure coherence and consistency between different requirements. The second reason is to speed up possible re-certification. A recertification is necessary because gateway adaptation or installation in a new environment. The European project certMILS deals with the issue of re-certification.
