The present invention is provided with a threat analysis processing unit that, on the basis of an analysis result from the vulnerability analysis unit, analyzes a threat to the system and outputs a threat analysis result; a countermeasure planning unit that, on the basis of the threat analysis result and vulnerability information, plans the countermeasure plan which reduces the impact of the vulnerability; a security test planning unit that plans the security test on the basis of the countermeasure plan; an evaluation calculation unit that performs an evaluation on the basis of the security test, and outputs an evaluation result; and a result processing unit that processes the evaluation result and generates a security countermeasure.

Risk evaluation and countermeasure planning system, and risk evaluation and countermeasure planning method

A security design planning support device which supports planning of a security design of an in-vehicle network, includes: a strategy policy creation unit which creates first strategy policy information representing a plurality of control strategies corresponding respectively to threats against the in-vehicle network; a merge processing unit which merges control strategies of a same type among the plurality of control strategies represented by the first strategy policy information created by the strategy policy creation unit and groups the plurality of control strategies; and a communication unit which externally outputs second strategy policy information representing a relationship of the threats and the plurality of control strategies grouped by the merge processing unit.

Security design planning support device

An in-vehicle device is mounted on a vehicle capable of automated driving, and comprises an incident detection processing unit which acquires vehicle information representing a control state of the vehicle, and detects an incident that occurred in the vehicle based on the vehicle information.

In-vehicle device and incident monitoring method

An in-vehicle device includes: an acquiring unit that acquires comparison information; and a detecting unit that detects an abnormality in a positioning device based on position information on a host vehicle output from the positioning device mounted in the host vehicle and the comparison information different from the position information.

In-vehicle device and vehicle

A plurality of in-vehicle information collecting devices mounted on a plurality of vehicles; a center server to manage each in-vehicle information collecting device as a communication target; and a communication unit to relay communication between each in-vehicle information collecting device and the center server are included. Each in-vehicle information collecting device has an in-vehicle controller to transmit/receive information including vehicle information to/from the center server, and the center server includes a server controller to transmit/receive information to/from each in-vehicle controller. The server controller, when receiving the vehicle information from each in-vehicle controller, analyzes the received vehicle information, generates speed information defining a transmission speed of the vehicle information based on an analysis result, and transmits the generated speed information to each in-vehicle controller. Each in-vehicle controller controls a communication amount of the vehicle information to the server controller, based on the speed information received from the server controller.

Information communication system, information communication method, and server

The present invention is directed to solve a problem that time is required for a process related to verification of a public key certificate of a message sender. An in-vehicle device mounted on a vehicle has a memory for holding information of a device which failed in verification of a public key certificate. At the time of performing communication between vehicles or between a vehicle and a roadside device, a check is made to see whether or not information of a device included in a message transmitted matches information of a device which failed and held in the memory. When the information matches, verification of a public key certificate is not performed.

In-vehicle communication system with verification failure holding circuit

In-vehicle communication system

If identification information is updated periodically, there is such a problem that when another vehicle is receiving driving support based on transmitted identification information of an own vehicle, if the identification information of the own vehicle is updated, the operation of driving support using the identification information becomes unstable because another vehicle can no longer identify the own vehicle. A mobile terminal mounted on a vehicle determines whether or not transmission control of identification information is necessary after determining the possibility of identification information misuse, determining the effect by controlling transmission of identification information, and determining the magnitude of adverse influence on the safe driving support service.

Mobile terminal

Communication equipment that received transfer data including data to be transferred, position information of a destination of the data to be transferred, position information of relay points used to determine a route to the destination, and position information of a last transferring vehicle determines a standby time that becomes shorter as a distance between the position of the last transferring vehicle and the position of a host vehicle becomes longer in the case where the host vehicle is not located in a predetermined range on the basis of the relay points. In addition, the communication equipment determines the standby time that becomes longer as a distance between the position of the host vehicle and the position of the relay point becomes longer in the case where the host vehicle is located in the predetermined range, and performs a process of transmitting the transfer data after the standby time passes.

Communication equipment, inter-vehicle communication control method and inter-vehicle communication system

The present invention provides a vehicle communication system by which even when the number of other vehicles around a traffic line is increased, it is possible to prevent occurrence of a situation that there are located vehicles the number of which is larger than the capacity of a communicable network, and it is possible to secure communications with the other vehicles. Even when it is determined that a host vehicle enters in a traffic line and a plurality of other vehicles the number of which is larger than a threshold value are located in front and rear virtual regions of the host vehicle, a transmission power is reduced to the extent that communications between the host vehicle and one of the other vehicles that is located furthest in the virtual regions can be secured.
