Abstract
A method for operating a railway system. Cryptographic data which includes at least one key and/or at least one digital certificate is stored in a storage device of a vehicle of the railway system. The vehicle transmits the cryptographic data to at least one track-side device of the railway system when the vehicle is in communication range of the least one track-side device as part of the train travel. There is also described a corresponding rail vehicle of a railway system.
Claims17
A method of operating a railway system, the method comprising:
- transmitting cryptographic data including at least one key from a central communication device to an on-board communication device of a vehicle of the railway system;
- storing the cryptographic data in a storage device of the vehicle of the railway system, the cryptographic data including the at least one key, the vehicle being configured to transport the cryptographic data in its storage device;
- and
- transmitting the cryptographic data including the at least one key from the vehicle to at least one track-side device of the railway system when, on occasion of a journey of the vehicle, the vehicle is present within a communication range of the at least one track-side device;
- replacing a key stored in the at least one track-side device with the at least one key transmitted to the at least one track-side device by the vehicle, ensuring a secured communication;
- implementing procedures comprising a plurality of communication steps on occasion of at least one further journey of the vehicle or at least one further vehicle;
- transmitting a report of the state of a local IT security at the at least one track-side device from the at least one track-side device to the vehicle or the further vehicle, and storing the report in the storage device of the vehicle;
- and
- transmitting the report from the vehicle or the further vehicle to the central communication device.

A vehicle of a railway system, the vehicle comprising:
- an on-board communication device configured to receive cryptographic data including at least one key from a central communication device;
- a storage device configured to store the cryptographic data with the at least one key, the vehicle being configured to transport the cryptographic data in its storage device;
- a control device for detecting that the vehicle is present within a communication range of at least one track-side device of the railway system during a journey;
- and
- a communication device configured for transmitting the cryptographic data including the at least one key to the at least one track-side device;
- replacing a key stored in the at least one track-side device with the at least one key transmitted to the at least one track-side device by the vehicle, ensuring a secured communication;
- the railway system being configured to implement a plurality of communication steps on occasion of at least one further journey of the vehicle or at least one further vehicle;
- the at least one track-side device being configured to transmit a report of the state of a local IT security at the at least one track-side device, to the vehicle or the further vehicle the report being stored in the storage device of the vehicle, and the report being transmitted from the vehicle or the further vehicle to the central communication device.
