“…Yasin et al improved on the work through inserting more pairwise keys [5]. In [23], IC protection is done by insertion of process variation (PV) sensors inside the design at specific selected nodes along with generation of a unique key for each IC. The maximum achieved HD from this technique was around 18%.…”

Due to the outsourcing of chip manufacturing, countermeasures against Integrated Circuit (IC) piracy, reverse engineering, IC overbuilding and hardware Trojans (HTs) become a hot research topic. To protect an IC from these attacks, logic encryption techniques have been considered as a low-cost defense mechanism. In this paper, our proposal is to insert the multiplexer (MUX) with two cases: (i) we randomly insert MUXs equal to half of the output bit number (half MUX insertions); and (ii) we insert MUXs equal to the number of output bits (full MUX insertions). Hamming distance is adopted as a security evaluation. We also measure the delay, power and area overheads with the proposed technique.
