Title (EN) SYSTEM AND PROCESSES FOR DETECTING MALICIOUS HARDWARE
(FR) SYSTÈME ET PROCÉDÉ DE DÉTECTION DE MATÉRIEL MALVEILLANT
Abstract:
(EN) A system for detecting malicious hardware on a data communication network, such as a vehicle CAN bus. The system includes a teleprocessing device, an AC signal generating device, and an impedance measuring device. In a preliminary step, a set of impedance measurements of N reference AC signals is formed, and a threshold value is set. The signal generating device injects a set of N AC signals into the network bus and the bus impedance for each of the N frequencies is measured, wherein a set of impedance values of N RT-signals is formed. Then, each of the impedance values of the RT-signals and the impedance values of the respective reference AC signal are statistically compared, to thereby form a set of N comparison-results. Upon determining that any of the impedance values of the RT-signals is greater than the threshold, an alert is activated.
(FR) Un système de détection de matériel malveillant sur un réseau de communication de données, tel qu'un bus CAN de véhicule. Le système comprend un dispositif de télétraitement, un dispositif de génération de signal alternatif et un dispositif de mesure d'impédance. Dans une étape préliminaire, un ensemble de mesures d'impédance de N signaux AC de référence est formé, et une valeur de seuil est établie. Le dispositif de génération de signal injecte un ensemble de N signaux AC dans le bus réseau et l'impédance du bus pour chacune des N fréquences est mesurée, un ensemble de valeurs d'impédance de N signaux RT étant formé. Ensuite, chacune des valeurs d'impédance des signaux RT et les valeurs d'impédance du signal AC de référence respectif sont comparées statistiquement, pour ainsi former un ensemble de N résultats de comparaison. Lorsqu'il est déterminé que l'une des valeurs d'impédance des signaux RT est supérieure au seuil, une alerte est activée.
