System, method and computer program product for disabling malicious electronic control units

Abstract

A computer-implemented method of disabling a rogue ECU in a plurality of electronic control units (ECUs) in communication with a Controller Area Network (CAN) bus network by communicating with the plurality of ECUs and the CAN bus network is provided. performed by a communicating computing device, the method includes: detecting a malicious message transmitted by the malicious ECU through the CAN bus network, and injecting a plurality of bits through the CAN bus network to trigger a plurality of predefined errors, so as to The rogue ECU is disabled before the rogue ECU makes additional attempts to retransmit additional instances of the rogue message.

Description

technical field [0001] Some embodiments relate to the management of malicious activity, and more particularly, but not exclusively, to the management of malicious activity within a Controller Area Network (CAN) bus network optionally implemented within a vehicle. Background technique [0002] The past two decades have seen a tremendous growth in the implementation of electronic systems in vehicles. These systems are designed to control and / or monitor many aspects of vehicle operation, such as engine operation, driver assistance modules, steering controls, door opening and locking, speed sensors, light controls, safety mechanisms (e.g., ABS brakes, air bags, etc. )Wait. A communication means and a software protocol connected between vehicle electronic control units (ECUs) are implemented based on the CAN bus definition. The CAN bus defines the way to transfer data between different ECUs. [0003] ECUs connected according to the CAN bus definition are vulnerable to maliciou...
