More-than-Moore devices (MTM) devices and application platforms have their origin in the convergence of wireless technologies, advancements of microelectromechanical systems (MEMS) and digital electronics.  Such application platforms comprise many small, inexpensive single-function devices and sensors, with varying operating systems, CPU types, memory, etc.  How these devices connect to other devices, and the device-human interfaces, are changing how we work and live.  Hardware security for these interconnected devices is a critical design consideration, just like performance, power, and reliability.   However, due to increased globalization, the whole IC design flow and application phases are distributed world-wide, and the resultant reduced control over the IC life cycle make hardware security a serious concern. For example, hardware security threats in the integrated circuit (IC) supply chain, including hardware counterfeiting and intellectual property piracy cost the US economy more than $200 billion annually. 

This paper examines the current issues pertaining to the hardware security and how they could affect the overall security of MTM applications, such as the internet of things. Specifically, we review the ongoing industry-led activities aimed at mitigating the hardware threats through supply chain assurance.  The paper is illustrated with the ongoing work of the ITRS hardware security working group, the counterfeit risk mitigation efforts from iNEMI, and the High-Density Package User Group (HDPUG), as well as published standards from SEMI and the Open Group.  All these efforts are aimed at mitigating counterfeits in the electronics supply chain through product traceability and authentication. Finally, we will discuss how existing and emerging technologies can be used for product authentication throughout the supply chain.
