Abstract
(EN)
An abnormal vehicle detection server (10) is provided with: an abnormality score calculation unit (106) that detects suspicious behavior different from prescribed driving behavior on the basis of a plurality of pieces of vehicle information respectively received from a plurality of vehicles, the vehicle information being based on a vehicle log including the content of an event which has occurred in a vehicle system (20) mounted on a vehicle, and acquires, for each of the vehicles, an abnormality score indicating the possibility of reverse engineering performed on the vehicle; and an abnormal vehicle determination unit (108) that determines whether one vehicle is an abnormal vehicle on the basis of the abnormality score of the one vehicle among the vehicles and the statistical value of the abnormality scores of two or more vehicles among the vehicles.
(FR)
L'invention concerne un serveur de détection de véhicule anormal (10) comprenant : une unité de calcul de score d'anomalie (106) qui détecte un comportement suspect différent d'un comportement de conduite prescrit sur la base d'une pluralité d'éléments d'informations de véhicule respectivement reçus en provenance d'une pluralité de véhicules, les informations de véhicule étant basées sur un journal de véhicule comprenant le contenu d'un événement qui s'est produit dans un système de véhicule (20) monté sur un véhicule et acquiert, pour chacun des véhicules, un score d'anomalie indiquant la possibilité d'ingénierie inverse effectuée sur le véhicule ; et une unité de détermination de véhicule anormal (108) qui détermine si un véhicule est un véhicule anormal sur la base du score d'anomalie du véhicule parmi les véhicules et de la valeur statistique des scores d'anormalité d'au moins deux véhicules parmi les véhicules.
(JA)
異常車両検出サーバ(10)は、車両に搭載された車両システム(20)において発生したイベント内容を含む車両ログに基づく車両情報であって複数の車両のそれぞれから受信した複数の車両情報に基づいて、所定の運転挙動とは異なる不審挙動を検出し、複数の車両のそれぞれについて、当該車両に対してリバースエンジニアリングが行われている可能性を示す異常スコアを取得する異常スコア算出部(106)と、複数の車両のうちの一の車両の異常スコアと複数の車両のうちの2以上の車両の異常スコアの統計値とに基づいて、一の車両が異常車両であるか否かを判定する異常車両判定部(108)とを備える。
