A Clock Sweeping Technique for Detecting Hardware Trojans Impacting Circuits Delay
Kan Xiao, Xuehui Zhang, Mohammad Tehranipoor · IEEE Design and Test · 2013
Clock sweeping can be used to generate signatures for the purpose of detecting hardware Trojans. With the help of simulations and FPGA results, this article demonstrates the effectiveness of their proposed clock-sweeping technique under process variations, even for Trojans as small as a few gates.
