A method of theft protection for computers and computer related hardware. Warranty fraud, theft of proprietary technology, and hardware theft are minimized by encoding the hardware components such that a digitally authenticated handshake must be performed between the system and the component at power-up. If the handshake is successful, normal operation continues with all enhancements. If the handshake is unsuccessful, the device is disabled or shifted into a lower performance mode.
