Abstract
A tamper detection system for a control module of a vehicle comprises first nonvolatile memory that stores N rewriteable components including at least one of calibration and software that is used to operate a controlled device of the vehicle, wherein N is an integer greater than zero. The N rewriteable components include an embedded part number (EPN) and an embedded verification number (EVN). Second nonvolatile memory includes a history buffer. A tampering detection module includes a calculated verification number (CVN) generator that generates a CVN for at least one of the N rewriteable components and that stores the CVN in the history buffer. A locking module selectively locks the history buffer under certain conditions.
