What is ERTMS?

ERTMS, or European Rail Traffic Management System, is a standard for railways deveoped by the European Union and used worldwide. This system is designed to improve signaling interoperation and management.  ERTMS requires the use of standardized equipment for signaling and safety protocols. With its emphasis on advanced command and control and interoperable technology, ERTMS aims to replace diverse localized systems.

Why is it Important to Protect ERTMS Systems?

ERTMS uses outdated GSM-R

The wireless link of ERTMS is based on the unsecured GSM-R standard.

Built in EuroRadio is not sufficient

EuroRadio, the ERTMS authentication layer, is based on an outdated cryptographic function 3DES.

Movement authority is provided wirelessly

Safety critical functions, such as movement authority commands, are provided through vulnerable wireless communications.

How We Can Help Protect Your ERTMS Systems?
