Abstract

A method of verifying data integrity performed by on-board equipment in a vehicle, the method comprising:

• • sending data for signing to an electronic chronotachograph on board said vehicle;
  • receiving a signature of said data from said electronic chronotachograph;
  • storing said data and said signature; and
  • transmitting the stored data and signature to a verification device.

Claims

1. A data storage method performed by on-board equipment in a vehicle, the method comprising:

sending data for signing to an electronic chronotachograph on board said vehicle;

receiving a signature of said data from said electronic chronotachograph;

storing said data and said signature; and

transmitting the stored data and signature to a verification device.

2. A storage method according to claim 1, wherein the process of sending data comprises sending to the electronic chronotachograph at least one data submission request message together with at least some of the data for signing.

3. A storage method according to claim 2, wherein the process of sending data comprises sending to the electronic chronotachograph a message requesting the transfer of a signature for data that is sent together with said at least one data submission request.

4. A storage method according to claim 2, wherein the format of said data submission request message and/or of the data signature request message complies with the standardized protocol described in Annex 1B of Regulation (EEC) No. 3821/85, the byte “

TRTP”

of said message presenting a value that is not defined in said standardized protocol.

5. A computer program including instructions for executing the storage method according to claim 1 when said program is executed by a computer.

6. A non-transitory computer readable storage medium including instructions of a computer program according to claim 5.

7. Equipment for use on board a vehicle, the equipment comprising:

a module configured to send data for signing to an electronic chronotachograph on board said vehicle;

a module configured to receive a signature of said data from said electronic chronotachograph;

a module configured to store said data and said signature; and

a module configured to transmit the stored data and signature to a verification device.

13. A vehicle including on-board equipment according to claim 7.

14. The vehicle of claim 13 comprising an electronic chronotachograph connected to said on-board equipment.

8. A signing method performed by an electronic chronotachograph on board a vehicle, the method comprising:

receiving data for signing from equipment on board said vehicle;

determining a signature for said data; and

of sending said signature to said on-board equipment.

9. A signing method according to claim 8, wherein the process of receiving data comprises receiving at least one message of format in compliance with the standardized protocol described in Annex 1B of Regulation (EEC) No. 3821/85, the byte “

TRTP”

of said message presenting a value that is not defined in said standardized protocol.

10. The method according to claim 8, wherein the method includes software executed by a computer.

11. A non-transitory computer readable data medium including instructions of a computer program according to claim 10.

12. An electronic chronotachograph for use on board a vehicle, the chronotachograph comprising:

a module configured to receive data for signing from equipment on board said vehicle;

a module configured to determine a signature for said data; and

a module configured to send said signature to said on-board equipment.
