An in-vehicle information processing apparatus includes a client processing unit configured to be provided with a service and perform processing, the client processing unit receives, from a server processing unit configured to provide a service, a service providing message that includes identification information and version information of a service to be provided, determines whether or not the version information included in the received service providing message and version information of a service that the client processing unit desires to be provided match, and, if it is determined that the two types of version information do not match, the client processing unit examines whether or not it is possible to receive the service with different version information, and, if it is possible to receive the service with different version information based on an examination result, the client processing unit receives the service and performs processing.

In-vehicle information processing apparatus, information processing method, and client program

In a relay apparatus, if partial data that is a portion of update data that is used to update a control program is input to a second input/output unit, a control unit stores the partial data in a storage unit. If partial data is input to a first input/output unit while partial data is being repeatedly input to the second input/output unit, the control unit stops storing the partial data input to the second input/output unit and stores the partial data input to the first input/output unit in the storage unit.

Storing apparatus, communication system, storing method, and computer program

In a relay device, a transmitting/receiving unit of an ECU relay receives data. A first counter value is incremented if an amount of data received by the transmitting/receiving unit per unit time exceeds a first threshold. A second counter value is incremented if the amount of data received by the transmitting/receiving unit per unit time exceeds a second threshold. The second threshold is greater than the first threshold. A control unit of a bus relay repeatedly monitors the first counter value. If the first counter value is incremented, the control unit shortens a cycle with which the second counter value is monitored.

Receiving device, monitor and computer program

Provided are an on-board update device, an update process method, and an update process program capable of appropriately updating a plurality of on-board devices installed in a vehicle if a plurality of update processes are provided through different paths. The on-board update device according to this embodiment performs communication via external communication units, and includes an execution determination unit configured to determine, if different update programs are respectively received from different external devices via a plurality of external communication units, based on version information of the update programs, whether or not it is possible to perform an update process using each update program, and, if the execution determination unit has determined that it is possible to perform update processes with regard to a plurality of update programs, an update process unit performs update processes using the plurality of update programs in parallel.

A communication system and a comparison method for securing a communication path for a legitimate user via a terminal apparatus ('TA'). A vehicle-mounted communication device ('VMCD') transmits a device ID identifying the VMCD to a TA, acquires a terminal ID from the TA, and transmits the device ID and the terminal ID acquired from the TA to a central apparatus. The TA transmits a terminal ID identifying the TA to the VMCD, acquires a device ID from the VMCD, and transmits the terminal ID and the device ID acquired from the VMCD to the central apparatus. The central apparatus receives a device ID and a terminal ID transmitted from the VMCD and a device ID and a terminal ID transmitted from the TA, and compares the device ID and the terminal ID received from the VMCD with the device ID and the terminal ID received from the TA.

In-vehicle communication system having a comparison means for verifying data and a comparison method for verifying data

An access restriction device as well as an on-board communication system and a method for communication restriction, which prevent outside leakage of information caused by unauthorized access of malicious programs to an in-car network. The communication between the in-car network of the vehicle and an external device is performed by a security controller. The security controller can perform addition or update of a program involving processing for transmission and reception of the information. The security controller performs processing for restricting access to information of the in-car network performed by program execution according to an access authorization level of each program and an access permission level of each type of information. The security controller restricts the transmission depending on the access authorization level of each program and the access permission level of each type of information in case of transmitting the information to the in-car network by the program execution.
