Optical scrambler having pyramids |
| abstract |
A pyramid structure to mitigate optical probing attacks in ICs by scrambling the measurements reflected by a laser pulse is disclosed. The pyramid structure is applied to selected areas at the bottom surface of the metal traces in metal layer to circumvent the extra silicon layer and thus minimize the changes to the conventional device structures. The pyramid structure includes randomized pyramids at nanometer scale. Optical simulation results show the pyramidized metal surface is able to prevent optical probing attacks. The fabrication of pyramids is CMOS compatible as well. Optical simulations are performed to analyze the impact these nano-scaled pyramids in a laser voltage probing attacking model. The nanopyramid can disturb the optical measurements enough to make the attacks practically infeasible. In addition, the nanopyramid structure countermeasure works in a passive mode without consuming any energy. |
