A first authentication process unit and a second authentication process unit of an ECU constituting a system respectively perform a first authentication process and a second authentication process for comparing authentication information acquired from a maintenance operator terminal and a user terminal, and first authentication information of a first authentication information registration unit and second authentication information of a second authentication information registration unit. An authority setting unit performs an operation permission for a vehicle for the purpose of maintaining the vehicle when the authentications match.

Vehicle control system

A communication system includes a communication device configured to execute a process related to a cyber security solution in accordance with policy information defining execution details of the process related to the cyber security solution. The communication system includes a change unit configured to change the policy information, wherein the change unit changes the policy information after a state of the communication device in a process of manufacturing the communication system transitions from a first state where the communication device is mounted to the communication system to a second state where a predetermined process is executed thereafter so that the execution details of the process related to the cyber security solution in the second state are expanded more than the execution details in the first state.

Communication system, moving object, and communication method

A communication apparatus of an embodiment includes: a communication unit that is capable of communicating with a first communication path and a second communication path; and a communication control part that controls the communication unit and that transmits a signal to the second communication path based on a signal which is received from the first communication path, wherein when a number of signals that are received from the first communication path in a first predetermined time span is more than a predetermined number, the communication control part performs a control such that a relationship between a number mof signals which are received from the first communication path and a number mof signals which are transmitted to the second communication path becomes m&#x3e;m

Communication apparatus, communication method, and program

While software in a relay device is being rewritten by an external diagnosis device, a processing unit of the relay device prohibits transfer processing of data from each ECU connected to CAN bus and allows transfer processing of data, which is transmitted from the external diagnosis device and which indicates at least either one of transmission prohibition of periodic transmission data and storage prohibition of a failure code into each ECU by not receiving the periodic transmission data in each ECU, to the CAN buses.

Relay device

In an onboard gateway apparatus, when data is received from one network, the received data is stored in the buffer. The buffer includes a first storage area for storing data in the order of priority of an identifier (ID) attached to the data and a second storage area for storing data in the order in which the data is received. A control means stores the received data in one of the first and second storage areas based on the attached identifier, and sends the data to another network in accordance with the priority of the ID of the data. As to data passing through the first storage area, sending in the order of priority is ensured. As to data passing through the second storage area, sending in the order in which the data is received is ensured.
