A computing module is described herein, wherein the computing module is configured to perform acts including generating a digital signature for a printed circuit board (PCB), wherein the digital signature is based upon a sensor signal generated by a sensor that is electrically coupled to at least one of a trace of the PCB or an electrical component of the PCB. The acts further include determining that the PCB is authentic and is free of tampering based upon the digital signature. The acts additionally include outputting an indication that the PCB is authentic and is free of tampering responsive to determining that the PCB is authentic and is free of tampering.
