Problems solved by technology

Such an attack may occur in such a control system: an illegally installed ECU or an ECU hijacked by a server attack sends false frames such as frames whose data content has been tampered with, thereby causing other ECUs to perform illegal control

Embodiment approach

[0065] [1 Outline of Vehicle Abnormality Detection System]

[0066] First, the outline of the vehicle abnormality detection system in the embodiment will be described using an example. figure 1 It is a block diagram showing an example of the service system of the vehicle abnormality detection system.

[0067] The vehicle anomaly detection system in this example includes: a plurality of vehicles 1010 located at users (service users) 1000 who receive information security services, a cloud server 1110 under the management of a data center operating company 1100, and a cloud server 1110 under the management of a data center operating company 1100 , and providing the above information security services as a The server 1210 under the management of the service provider 1200 of the business.

[0068] The first vehicle and the second vehicle are examples of the vehicle 1010, and each is an automobile equipped with an in-vehicle network. A gateway 1020 is included in each in-vehicle n...

Abstract

Equipped with: the communication unit (810), which communicates with the vehicle, and receives the log of the vehicle-mounted network that the vehicle has; In the case of the abnormality information in the first vehicle, select the abnormality-related vehicle corresponding to the abnormality from multiple vehicles; the log collection unit (830) sends a request to the abnormality-related vehicle via the communication unit (810). a first request for a log of an in-vehicle network mounted on the abnormality-related vehicle; and the log analysis unit (840), based on the information indicated by the log sent from the abnormality-related vehicle and received by the communication unit (810) according to the first request, It is determined whether or not an abnormality has occurred in the abnormality-related vehicle.

Description

technical field [0001] The present invention relates to a security technology for detecting and responding to attack frames that can be transmitted in an in-vehicle network in which an electronic control unit mounted on a vehicle communicates. Background technique [0002] In recent years, a plurality of devices called electronic control units (ECU: Electronic Control Units) have been installed in automobiles. The communication network connecting these ECUs is called the in-vehicle network. As main communication standards applied to the in-vehicle network, a Controller Area Network (CAN (registered trademark)) and Ethernet (registered trademark) defined in ISO11898-1 can be cited. With the increase in performance of automobiles, functions for determining and providing the content of control performed by each ECU based on data transmitted and received between ECUs via such an in-vehicle network are gradually increasing. Such attacks may occur in such a control system: an il...
