Abstract
A method for trusted recording in a road toll system, the road toll system having a proxy server connected via a mobile network to an onboard-unit of a vehicle, the onboard-unit having a position determination device, comprising: creating an itinerary record comprising a first or second position, a first or second point of time at least one of: a distance calculated using at least the first and second position, a segment-id, and a distance calculated using said segment-id; receiving and recording a signed itinerary record from the proxy server. In a further aspect of the embodiment an onboard-unit and a proxy server are provided for trusted recording in a road toll system.
Claims20
A method for trusted recording in a road toll system, the road toll system having a proxy server connected via a mobile network to an onboard-unit of a vehicle, the onboard-unit having a position determination device for determining a current position of the vehicle, the onboard-unit having no trusted element, comprising the following steps performed in the onboard-unit:
- determining a first position by means of the position determination device at a first point of time and a second position by means of the position determination device at a second point of time;
- creating an itinerary record comprising the first or second position, the corresponding first or second point of time and at least one of:
- a distance calculated using at least the first and second position, a segment-id calculated using at least the first or second position, and a distance calculated using said segment-id;
- sending the itinerary record via the mobile network to the proxy server;
- receiving a signed itinerary record from the proxy server, and
- recording said signed itinerary record in a memory of the onboard-unit;
- the method further comprising the step of signing the itinerary record in a trusted element of the proxy server with a digital signature.
An onboard-unit for mounting on a vehicle in a road toll system, the onboard-unit comprising:
- a position determination device for determining a current position of the vehicle;
- a memory;
- a transceiver for communication with a proxy server via a mobile network;
- and
- a processor coupled to the memory, the position determination device and the transceiver;
- the onboard-unit having no trusted element;
- wherein the processor is configured to
- determine a first position by means of the position determination device at a first point of time and a second position by means of the position determination device at a second point of time,
- create an itinerary record comprising the first or second position, the corresponding first or second point of time and at least one of:
- a distance calculated using at least the first and second position, a segment-id calculated using at least the first or second position, and a distance calculated using said segment-id,
- send the itinerary record via the transceiver to the proxy server, receive a signed itinerary record from the proxy server via the transceiver, wherein the itinerary record was signed in a trusted element of the proxy server with a digital signature, and
- record said signed itinerary record in the memory.
A proxy server for a road toll system, the proxy server comprising
- a transceiver for communication via a mobile network with an onboard-unit carried by a vehicle);
- a trusted element;
- and
- a processor coupled to the transceiver and the trusted element;
- wherein the processor is configured to
- receive, via the transceiver, an itinerary record comprising a first or second position, a corresponding first or second point in time and a distance based on at least the first and second position from the onboard-unit,
- let the received itinerary record have signed by the trusted element with a digital signature, and
- send the signed itinerary record from the proxy server via the transceiver to the onboard-unit.
