Abstract
Systems, methods, and vehicles for verifying integrity of automotive software. In one implementation, an electronic processor is configured to receive a power-up signal and randomly select one of a plurality of fingerprints. The electronic processor is also configured to retrieve a set of data stored in the memory cells of the selected fingerprint. The electronic processor is further configured to calculate a pre-boot verification value for the selected fingerprint using a one-way cryptographic function with a secret key and the retrieved set of data. The electronic processor is also configured to compare the pre-boot verification value to a reference verification value for the selected fingerprint. The electronic processor is further configured to release a security halt on the software image when the pre-boot verification value matches the reference verification value for the selected fingerprint.
