Abstract: The present invention relates to the field of ensuring the safety of vehicles, namely, to the system and method of protecting electronic control systems of vehicles. The system of protection of electronic control systems of vehicles from unauthorized intrusion includes at least one electronic module of the vehicle and a device for protecting the vehicle control system connected via electrical conductors to the interface communication line. The protection device of the vehicle control system consists of 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.

Abstract: The invention relates to the field of providing security to vehicles, specifically to a system and a method for detecting the connection of unauthorized devices. A system for detecting unauthorized connected devices in a vehicle comprises at least one electronic device of the vehicle, which is connected via an electrical bus to a module for detecting unauthorized devices consisting of a measurement unit, an analog-digital converter, a digital signal processing unit, a buffer unit and a comparator unit. A method for detecting unauthorized devices includes measuring the parameters of an electrical signal at a first moment and a second moment in time, with subsequent formation of an electrical signal spectrum. The electrical signal spectrum at the first moment in time is set as a threshold, on the basis of which a comparison is made with that received in the second time period. The accuracy of detecting unauthorized connected devices is increased.
