About the project

The railway companies DB, SNCF, NS, ÖBB and SBB have joined forces in the OCORA (Open CCS On-board Reference Architecture) initiative to define architecture and interfaces for the next generation of ETCS (European Train Control System) on-board equipment. The aim of the initiative is to create the basis for safety-related applications on the vehicle side.

A standardised separation of applications and hardware platforms will be introduced, such that the different life cycles of both domains can be decoupled. In this way, the latest developments in the IT sector can also be used for the railway.

The primary motivation behind this approach is better interchangeability through modularity and easier updating and expansion of the vehicle-side installations throughout the entire vehicle life cycle.

Our contribution

As Cyber Security Manager, Enotrac was responsible for the cyber security process of the on-board train protection system in accordance with TS50701 and IEC62443. In order to be able to guarantee compliance with the standards, significant influence was exerted on the system architecture.

Enotrac’s main objective in the process was to define the relevant cyber security requirements for the CCS system and its subsystems.
