In-vehicle device, information processing method, and in-vehicle system

An in-vehicle device communicatively connected to an in-vehicle ECU mounted in a vehicle, the in-vehicle device comprising:

• a controller configured to perform processing related to a service request from the in-vehicle ECU,
• wherein the controller is configured to:
• acquire request data related to the service request from the in-vehicle ECU,
• specify a service provided to the in-vehicle ECU and a security level when providing the service based on the acquired request data,
• generate provision data for providing a service to the in-vehicle ECU based on the specified security level,
• output the generated provision data to the in-vehicle ECU, and
• specify a security level by referring to a service table stored in an accessible storage area and including setting information related to a security level,
• the service table includes a name of an application executed by the in-vehicle ECU, and
• the acquired request data includes the name of the application executed by the in-vehicle ECU, and
• specifies a security level by referring to the service table based on the name of the application included in the acquired request data.

An information processing method causing a computer communicatively connected to an in-vehicle ECU mounted in a vehicle to execute processing of:

• acquiring request data related to a service request from the in-vehicle ECU,
• specifying a service provided to the in-vehicle ECU and a security level when providing the service based on the acquired request data,
• generating provision data for providing a service to the in-vehicle ECU based on the specified security level,
• outputting the generated provision data to the in-vehicle ECU, and
• specifying a security level by referring to a service table stored in an accessible storage area and including setting information related to a security level,
• the service table includes a name of an application executed by the in-vehicle ECU, and
• the acquired request data includes the name of the application executed by the in-vehicle ECU, and
• specifies a security level by referring to the service table based on the name of the application included in the acquired request data.

An in-vehicle system comprising:

• an in-vehicle ECU mounted in a vehicle;
• and
• an in-vehicle device communicatively connected to the in-vehicle ECU, wherein:
• the in-vehicle ECU is configured to:
• generate request data related to a service request, and
• output the generated request data to the in-vehicle device, and
• the in-vehicle device is configured to:
• acquire the request data from the in-vehicle ECU,
• specify a service provided to the in-vehicle ECU and a security level when providing the service based on the acquired request data,
• generate provision data for providing a service to the in-vehicle ECU based on the specified security level,
• output the generated provision data to the in-vehicle ECU, and
• specify a security level by referring to a service table stored in an accessible storage area and including setting information related to a security level,
• the service table includes a name of an application executed by the in-vehicle ECU, and
• the acquired request data includes the name of the application executed by the in-vehicle ECU, and
• specifies a security level by referring to the service table based on the name of the application included in the acquired request data.
