Abstract:

Semiconductor supply chain is increasingly getting exposed to variety of security attacks such as Trojan insertion, cloning, counterfeiting, reverse engineering RE, piracy of Intellectual Property IP and side-channel analysis due to involvement of untrusted parties. Camouflaging of gates has been proposed to hide the functionality of fates. However, camouflaging is associated with significant area, power and delay overhead. In this paper, we propose camouflaging of interconnects using multiplexers muxs to protect the IP. A transistor threshold voltage-defined pass transistor multiplexer is proposed to prevent its reverse engineering since transistor threshold voltage is opaque to the adversary. The proposed pass transistor based multiplexer having more than one input, hides the original connectivity of the net.
