Abstract
An Electronic Control Unit (ECU) provides security for an automotive system. The ECU is classified according to a Cybersecurity Assurance Level (CAL) and calculates a cryptographic value for one or more or all modules of the ECU. The calculated cryptographic value is compared with a stored cryptographic value. Based on the CAL classification of the ECU, either control to one or more modules of the ECU is provided or the ECU is shut down as follows: when the calculated cryptographic value matches the stored cryptographic value, control to the one or more or all modules of the ECU is provided; and, when the calculated cryptographic value does not match the stored cryptographic value, the ECU is shut down in one of a current boot cycle or a subsequent boot cycle.
