PROBLEM TO BE SOLVED: To provide a technique capable of detecting an attack through communication, in a system in which a vehicle receives information from the outside through the communication.SOLUTION: An attack detection system comprises a server device and a plurality of vehicles that are capable of radio communication with each other. Each of the plurality of vehicles comprises: a sensor; sensor information acquisition means for acquiring sensor information from the sensor; road traffic information reception means for receiving road traffic information by radio communication; and transmission means for transmitting the sensor information and the road traffic information to the server device. The server device comprises: reception means for receiving the sensor information and the road traffic information from at least any of the plurality of vehicles; verification means for checking to see if the sensor information and the road traffic information contradict each other; and notification means for notifying at least any of the plurality of vehicles if the sensor information and the road traffic information contradict each other.SELECTED DRAWING: Figure 1

    【課題】車両が外部から通信により情報を受信するシステムにおいて、当該通信による攻撃を検知可能な技術を提供する。【解決手段】互いに無線通信可能なサーバ装置と複数の車両とから構成される攻撃検知システムであって、前記複数の車両の各々は、センサと、前記センサからセンサ情報を取得するセンサ情報取得手段と、無線通信により交通情報を受信する交通情報受信手段と、前記センサ情報および前記交通情報を前記サーバ装置へ送信する送信手段と、を備え、前記サーバ装置は、前記複数の車両の少なくともいずれかから前記センサ情報および前記交通情報を受信する受信手段と、前記センサ情報と前記交通情報の間に矛盾があるか否かを検証する検証手段と、前記センサ情報と前記交通情報の間に矛盾がある場合に、前記複数の車両の少なくともいずれかに通知する通知手段と、を備える。【選択図】図1
