    摘要: A method, program product and apparatus include resistance structures positioned proximate security sensitive microchip circuitry. Alteration in the position, makeup or arrangement of the resistance structures may be detected and initiate an action for defending against a reverse engineering or other exploitation effort. The resistance structures may be automatically and selectively designated for monitoring. Some of the resistance structures may have different resistivities. The sensed resistance may be compared to an expected resistance, ratio or other resistance-related value. The structures may be intermingled with false structures, and may be overlapped or otherwise arranged relative to one another to further complicate unwelcome analysis.
