[0065] [1. Overview of V2X network]
[0066] First, an overview of a V2X network to which the technology according to the present invention can be applied will be described. figure 1 It is a figure for explaining the outline|summary of a V2X network.
[0067] Nodes constituting the V2X network 1 include vehicles 10A, 10B, and 10C, a traffic light 30A, a vehicle speed meter 30B, a base station 40 , and an abnormality monitoring server 50 . In addition, below, vehicles 10A, 10B, and 10C may be referred to as a vehicle 10 collectively or referring to arbitrary one or more without distinction. In addition, the signal lamp 30A and the vehicle speed measuring device 30B may be collectively referred to as the roadside device 30 without distinguishing them.
[0068] The vehicle 10 performs V2V communication with the vehicle 10 and V2I communication with the roadside device 30 , and transmits and receives data using, for example, a predetermined message set such as BSM (Basic Safety ...

An abnormality determination device (125) which is included in a first node being monitored in a network, and includes a processor that: acquires log information, which includes the time of day and information about the state of the first node at the relevant time of day, as indicated by sensor data or control data at the first node; executes a first abnormality determination related to the occurrence of an abnormality in the first node at the relevant time of day; executes a second abnormality determination related to the occurrence of an abnormality in a second node at the relevant time of day, on the basis of second node information acquired from a second node and related to an abnormality in the second node, which is a node that is in the vicinity of the first node and is another monitoring subject; and, when an abnormality has occurred in the second node, appends abnormality information indicating that an abnormality has occurred in the second node to the log information, and transmits the log information to at least a portion of the nodes on the network.
Description
technical field [0001] The invention relates to a V2X network that uses an anomaly detection model to perform anomaly judgment. Background technique [0002] The communication paths with the outside used by increasingly high-performance automobiles are not limited to communication paths via mobile communication lines such as LTE (Long Term Evolution) and are increasing. The V2X (meaning Vehicle-to-everything) network assumes that vehicles driving on the road communicate with other vehicles, traffic infrastructure such as traffic lights, pedestrians’ smartphones, and other surrounding objects, oriented to the realization of V2X networks The practical application of advanced technologies has gradually brought into view the realization of more intelligent autonomous driving. [0003] On the other hand, the risk of cyber attacks also increases for the vehicle-mounted network system of a car that receives information from more routes including the outside. In order to realize t...
