Abstract

An on-board communication device, an on-board communication system, and a specific processing prohibition method for a vehicle, in which a specific service can be prevented from being provided without limitation is disclosed. The on-board communication system can perform update processing of a relay processing program for a gateway using a wireless communication path through a wireless communication device or a communication path through a communication cable connected to a connector unit. When receiving an authentication request through either of the two communication paths, the gateway performs authentication processing, and if the authentication processing was successful, the gateway receives an update relay processing program through this communication path, and performs update processing by overwriting a stored relay processing program. At this time, the gateway prohibits update processing through any communication path other than the communication path through which the authentication processing was performed.

Claims

1. An on-board communication device that is mounted in a vehicle and is provided with a plurality of communication processing units that each perform communication processing through a predetermined communication path, the on-board communication device comprising:

an authentication processing unit that performs authentication processing with another device when there is an authentication processing request from the other device through one communication path;

a specific processing unit that performs specific processing with the other device through the one communication path if the authentication processing performed by the authentication processing unit was successful; and

a prohibition unit that prohibits the specific processing through any communication path other than the one communication path if the authentication processing performed by the authentication processing unit was successful.

2. The on-board communication device according to claim 1,

wherein the prohibition unit prohibits authentication processing with the authentication processing unit based on an authentication processing request given through any communication path other than the one communication path.

3. The on-board communication device according to claim 1,

wherein the specific processing performed by the specific processing unit is processing for updating a program or data stored in a device mounted in the vehicle using a program or data received from the other device through the one communication path.

4. The on-board communication device according to claim 1,

wherein the specific processing performed by the specific processing unit is processing for transmission/reception of information for operation verification, to/from the device mounted in the vehicle.

5. The on-board communication device according to claim 1,

wherein the plurality of communication paths through which the plurality of the communication processing units perform communication processing include a communication path through which wireless transmission/reception of information to/from a device outside of the vehicle is performed.

6. The on-board communication device according to claim 1,

wherein the plurality of communication paths through which the plurality of the communication processing units perform communication processing include a communication path through which transmission/reception of information is performed to/from another device that is attachably/removably connected to a connection unit provided in the vehicle, through the connection unit.

7. An on-board communication system provided with a plurality of communication devices that each perform communication processing through a predetermined communication path, the on-board communication system comprising:

an authentication processing unit that performs authentication processing with another device when there is an authentication processing request from the other device through one communication path;

a specific processing unit that performs specific processing with the other device through the one communication path if the authentication processing performed by the authentication processing unit was successful;

a prohibition unit that prohibits the specific processing through any communication path other than the one communication path if the authentication processing performed by the authentication processing unit was successful.

8. A specific processing prohibition method for a vehicle performed by an on-board communication device that is mounted in a vehicle and is provided with a plurality of communication processing units that each perform communication processing through a predetermined communication path, the specific processing prohibition method for a vehicle comprising:

performing authentication processing with another device when there is an authentication processing request from the other device through one communication path;

performing specific processing with the other device through the one communication path if authentication processing performed by the authentication processing unit was successful; and

prohibiting the specific processing through any communication path other than the one communication path if the authentication processing performed by the authentication processing unit was successful.
