System and method for protecting electronic vehicle control systems against hacking

Abstract

Techniques for protecting electronic vehicles control systems from unauthorized intrusion work with at least one electronic module of the vehicle and a protection device connected via electrical conductors to the interface communication line. The protection device includes a control unit for monitoring and control of vehicle parameters, a passive scanning of interface communication lines unit, a spectral analysis of interface communication lines unit, a unit for detection and suppression of malicious commands, and a unit for detecting and jamming in a given frequency range an unauthorized receiver/transmitter. The units for passive scanning of interface communication lines, spectral analysis, and detection and suppression of malicious commands are connected to the interface communication line. To detect unauthorized devices, the electrical parameters and the electrical signal of the interface communication line are measured, followed by construction of the signal spectrum in first and second time periods and their comparison.
