ABSTRACT:
A physical barrier for a circuit board also functions as a tampering sensor or sensors monitored by electrical circuitry that generates a tamper signal for erasing information critical for the operation of the circuit board in the event of sensed tampering. One or more routing matrices configured in at least one programmable device is programmed to interconnect operating as well as optional dummy components on the board so that routing information is erased in the event of sensed tampering.
