DescriptionMagnetic skyrmion has the potential to become one of the candidates for emerging technologies and is a magnetic pattern created by transverse current injection in the heavy metal (HM) layer and behaves like a stable pseudoparticle. In this paper, we propose novel camouflaged logic gate designs to prevent an adversary from extracting the original netlist. The proposal uses selective doping to block the propagation of the skyrmions to realize the camouflaged gates. We demonstrate the functionality of different camouflaged gates using the mumax3 micromagnetic simulator. We have also evaluated the security of the proposed camouflaged designs using SAT attacks.
