Abstract

A device and a method are provided for generating IPv6 addresses from a vehicle identification number VIN. The method carried out by the communication controller of the vehicle is used inside the vehicle to generate unique local IPv6 addresses for the on-board devices. The method also enables the generation of IPv6 addresses for communication to the outside of the vehicle.

Claims

1. A method for generating Internet Protocol (IP) addresses for entities connected to a communication controller via a communication network inside a vehicle, the vehicle being associated with a vehicle identification number (VIN), the method comprising the steps of:

encoding the content of one or more fields of the VIN in the decimal base and the content of one or more other fields of the VIN according to a non-random algorithm;

converting the result of the encoding into binary;

ordering the bits obtained according to a predefined sequence;

generating an interface identifier (IID) and an IP address prefix from the ordered sequence; and

constructing an IP address for each entity, each IP address including at least said generated prefix.

2. The method as claimed in claim 1, further comprising a step of sending a message to the entities of the vehicle to announce said prefix.

3. The method as claimed in claim 1 wherein the IP address constructed for each entity further includes an interface identifier based on the MAC address of each entity.

4. The method as claimed in claim 1, further comprising, before the encoding step, a step of selecting the fields of the VIN to be encoded.

5. The method as claimed in claim 4 wherein the selection step consists in selecting all the fields of the “

World Manufacturer identifier”

(WMI) section, all fields of the “

Vehicle Identification Section”

(VIS), and one or more fields of the “

Vehicle Description System”

(VDS) section.

6. The method as claimed in claim 5, wherein positions 4 and 5 of the VDS section are selected.

7. The method as claimed in claim 5, wherein the encoding step consists in encoding in the decimal base positions 10, 14, 15, 16 and 17 of the VIS section.

8. The method as claimed in claim 1, wherein the ordered sequence contains 51 bits.

9. The method as claimed in claim 1, further including a step of constructing at least one IP address for the communication controller, said at least one IP address including said interface identifier and at least one prefix generated by a system outside the internal communication network of the vehicle.

10. The method as claimed in claim 1, further comprising a step of constructing at least one IP address for the communication controller, said at least one IP address including at least said interface identifier and said prefix.

11. The method as claimed in claim 1, wherein the IP addresses are IPv6 addresses, and said prefix is a ULA prefix.

12. A system for generating Internet Protocol (IP) addresses for entities connected to a communication controller via a communication network within a vehicle, the vehicle being associated with a vehicle identification number (VIN), the system including means for carrying out the steps of the method as claimed in claim 1.

13. The system as claimed in claim 12, wherein the entities are suitable for communicating according to the TCP/IPv6 protocol and the generated addresses are IPv6 addresses.

14. The system as claimed in claim 12, wherein the communication controller includes internal interfaces and external interfaces to communicate on the generated IP addresses as claimed in any one of claims 1 to 11.

15. A computer program product, said computer program including code instructions enabling the steps of the method as claimed in claim 1 to be carried out, when said program is executed on a computer.
