System for intrusion detection using a vehicle electrical system

A system comprising:

• memory;
• a processor in a smart power distribution, wherein the processor is in communication with the memory and programmed to:
• compute a baseline fingerprint that includes a baseline measurement of a physical attribute of the smart power distribution system during an enrollment period of the system, wherein the enrollment period includes measuring the attribute of the smart power distribution system prior to runtime operation, wherein the smart power distribution system includes at least one set of non-safety critical consumer channels, at least one set of safety critical consumer channels, at least two different power sources connected to at least two power channels, wherein a first power source supplies power to the at least one set of non-safety critical consumer channels and a second power source supplies power to the at least one set of safety critical consumer-channels, and at least two switches separating the safety critical consumer channels and the non-safety critical consumer channels, wherein the at least one set of non-safety critical consumer channels and the at least one set of safety critical consumer channels can be individually shut off by the at least two switches;
• receive a runtime measurement of the physical attribute of the at least one set of non-safety critical consumer channels of the smart power distribution system during runtime;
• compute a runtime fingerprint utilizing the runtime measurement and compare the runtime fingerprint to the baseline fingerprint;
• and
• in response to the measurement exceeding a threshold, execute a countermeasure operation against software in communication with the smart power distribution system.
