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 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 a user (service user) 1000 receiving information security services, a cloud server 1110 managed by a data center operating company 1100, and a cloud server 1110 for providing the above information security services 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 are automobiles each equipped with an in-vehicle network. Each in-vehicle network includes a gateway 1020 . It is the driver D10 who actually drives the vehicle 1010 . Logs of data transceiv...

Abstract

This vehicle abnormality detection server is provided with: a communication unit (810) which communicates with a vehicle and receives a log of an in-vehicle network provided in the vehicle; a log collection object vehicle selection unit (855) which, when acquiring information indicating occurrence of an abnormality in a first vehicle that is one of a plurality of vehicles as communication partners, selects an abnormality-related vehicle corresponding to the abnormality from among the plurality of vehicles; a log collection unit (830) which transmits, to the abnormality-related vehicle via thecommunication unit (810), a first request requesting transmission of the log of the mounted in-vehicle network; and a log analysis unit (840) which, on the basis of information indicated by the log transmitted from the abnormality-related vehicle in response to the first request and received by the communication unit (810), determines whether or not the 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 that communicates with an electronic control unit mounted on a vehicle. Background technique [0002] In recent years, a plurality of devices called electronic control units (ECU: Electronic Control Unit) are installed in automobiles. The communication network connecting these ECUs is called the in-vehicle network. Main communication standards applied to in-vehicle networks include Controller Area Network (CAN (registered trademark)) and Ethernet (registered trademark) specified in ISO11898-1. With the increase in performance of automobiles, functions to determine and provide the content of control performed by each ECU based on data transmitted and received between ECUs via such an in-vehicle network are increasing. Such an attack may occur in such a control system: an illegally installed ECU or an ECU...
