Definitions

  • the invention relates to a method for transmitting data from a first station in a railway vehicle to a second station.
  • the second station is usually located at a fixed location, eg. B. in a train station or in a signal box. It can also be located in another railway vehicle.
  • Public communications networks are often used to transmit data from a railway vehicle and, in particular, to a stationary facility. This gives the possibility that an unauthorized group of persons may receive transmitted data. The same problem exists when the railway vehicle communicates with the second station over the radio for data transmission.
  • the invention has for its object to provide a method for transmitting data from a first station in a railway vehicle to a second station, which prevents the reading of data by unauthorized persons. Nevertheless, the great availability of public communication networks should not be left out.
  • the object is achieved according to the invention in that a signature is created in the first station and sent to the first station at the first station to the first, that received the signature of the second station, signed and then sent back to the first station and is stored there and that only then begins with the transfer of the data.
  • the advantage is achieved that the confidentiality of the data transmission is ensured. Only if the known signature of the second station arrives at the first station, it is ensured that the second station is the desired receiver. The data can not reach an unauthorized station.
  • the respective received signatures are checked and only if no errors are to be detected is the transmission of data begun. This provides the additional advantage that the integrity of the data transmission is always given. Advantageously, no erroneous data is transmitted.
  • one of the stations sends to the other station several suggestions for encryption algorithms, from which the other station selects one of the suggestions and sends the result back to the former station.
  • Signatures to be sent are then encrypted with the selected encryption algorithm. This provides the advantage of further improving the confidentiality of the transmitted data.
  • the receiving station sends the received data back to the transmitting station. If any data other than the data sent back, this would immediately indicate an error in the transmission and the data in question would not be considered.
  • the first station has, for example, a remote transmission gateway for transmitting and receiving data.
  • a remote transmission gateway enables a reliable data flow between the station in the railway vehicle and the individual components of the vehicle.
  • the second station may also have, for example, a long-distance transmission gateway for transmitting and receiving data.
  • the long-distance transmission gateway communicates with a train bus.
  • the train bus is connected, for example, with vehicle buses.
  • This provides reliable data streams from the components connected to the individual vehicle buses via the train bus and the long-distance transmission gateway to the station for data transmission.
  • logs sent from the train bus or from the vehicle bus are converted in the remote transmission gateway for transmission.
  • the second station is at a fixed location. It can be a railway station or a signal box.
  • the second station is integrated in a public communication network.
  • a public communication network When a fixed public communications network is used, no new connections are necessary between the second station and a traveling railway vehicle data transmitting and receiving station. But it can also be used a public communication network, which also reaches moving railway vehicles, for example a radio network.
  • the advantage is achieved that on the one hand unwanted transmission of data to an unauthorized recipient is largely excluded and beyond errors in the data transmission can be detected quickly and reliably.
  • railway vehicles of a train are connected to each other via a train bus.
  • individual vehicle buses which are located in the individual railway vehicles, are coupled via gateways.
  • Components are connected to the vehicle buses. Examples of components are the drive control or the braking device.
  • To connect the components to a vehicle bus are communication bus circuits.
  • a remote transmission gateway On the train bus is a remote transmission gateway, which is part of a first station for the transmission of data connected. Such a remote transmission gateway could also be connected to a vehicle bus.
  • a second station for transmitting the data is arranged, for example, at a fixed location and communicates via a public network with the first station in the railway vehicle.
  • a public network There are various radio networks of the public network possible, for. B. WLAN.
  • the second station when in a fixed location, can also communicate over a cable network followed by a radio network. It can be in the second station z.
  • a communication server a network of single-user systems, a communication router or a combination of these components may be present.
  • That the recipient is the desired addressee for the data is determined by sending a signature.
  • a signature is a string. If a signature is incorrect, the data will not be taken into account and an additional error message may be issued.
