Marcellus P Baines
Co Invented a motor vehicle engine immobilizer security system and patented it on 4/25/2006#7,034,654
Patent Abstract: Methods and apparatus are provided for insuring that a motor vehicle is being operated by an authorized operator. The apparatus includes an electronic control unit (ECU), an engine immobilizer unit, and a shared encryption key. The ECU generates a challenge by combining the output of a pseudo-random number generator and the output of a somewhat random number generator and cycling the combined number through a linear feedback shift register. The ECU sends the challenge to the immobilizer unit where it is encrypted with the shared key and sent back to the ECU as a response. The ECU uses the same key to encrypt the challenge and compares the encrypted challenge to the response. If the response matches the encrypted challenge, engine operation is enabled.

Diagnostic system and method for detecting tampering of vehicle software or calibrations
Patent number: 7894978
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.
