Tamzidul Hoque, Patanjali SLPSK, Swarup Bhunia · 2020
Commercial off-the-shelf (COTS) components, such as microcontrollers, processors, and field programmable gate arrays (FPGA) increasingly constitute the hardware backbone for modern electronic systems, including internet of things (IoT) devices. However, distributed untrusted supply chain of these components make counterfeiting and malicious alterations of these components easy and wide-spread phenomenon. In this paper, we address the various trust issues in COTS and present a list of promising design and verification solutions to address them.
