Title
(EN) METHOD OF DETECTING UNAUTHORIZED DEVICES INSTALLED ON ELECTRICAL INTERFACES OF VEHICLES
(FR) PROCÉDÉ DE DÉTECTION DE DISPOSITIFS NON AUTORISÉS INSTALLÉS SUR DES INTERFACES ÉLECTRIQUES DE VÉHICULES
Abstract
(EN)
This invention relates to cybersecurity enforcement in vehicle control systems, specifically, the protection of electrical interfaces as components of such control systems. The method of detecting unauthorized devices installed on electrical interfaces of vehicles comprises measuring the impedances (the reactive and the active resistances) of the electrical interface at the initial moment of time and subsequently. The measurement of the active component of the electrical interface resistance comprises the measurement of the current and voltage of the devices connected to the electrical interface followed by the calculation of the total resistance of all the devices. The measurement of the reactive component of the electrical interface resistance comprises the measurement of the capacitance component of the electrical interface resistance by the impedance spectroscopy method. The technical result of the invention disclosed herein is the prevention and elimination of the threat option, more specifically, the installation of unauthorized devices on electrical interfaces.

La présente invention concerne l'application de cybersécurité dans des systèmes de commande de véhicule, en particulier la protection d'interfaces électriques en tant que composants de tels systèmes de commande. Le procédé de détection de dispositifs non autorisés installés sur des interfaces électriques de véhicules consiste à mesurer les impédances (les résistances réactives et actives) de l'interface électrique à l'instant initial et ensuite. La mesure du composant actif de la résistance d'interface électrique comprend la mesure du courant et de la tension des dispositifs connectés à l'interface électrique suivie du calcul de la résistance totale de tous les dispositifs. La mesure du composant réactif de la résistance d'interface électrique comprend la mesure de la composante de capacitance de la résistance d'interface électrique par le procédé de spectroscopie d'impédance. Le résultat technique de l'invention est la prévention et l'élimination de l'option de menace, et plus particulièrement de l'installation de dispositifs non autorisés sur des interfaces électriques.
