Title:
ELECTRONIC CONTROL UNIT PROTECTION FRAMEWORK USING SECURITY ZONES
Document Type and Number:
WIPO Patent Application WO/2018/169666
Kind Code:
A3
Abstract:
Systems are provided herein for a hardware protection framework. A security module monitors a plurality of voltage lines of at least one electronic control unit (ECU) electrically coupled to a communications bus. A voltage differential across at least two of the plurality of voltage lines of the at least one ECU is measured. The voltage differential is compared to a plurality of predetermined signal fingerprints associated with the at least one ECU. A variance in the compared voltage differential is identified relative to one or more of the plurality of predetermined signal fingerprints. Data characterizing the identified variance is provided. In some aspects, a pulse or a data stream is injected based on the voltage differential having an amplitude lower than a predetermined voltage threshold.
