Hardware Security for and beyond CMOS Technology
This addresses hardware security challenges for electronic systems as CMOS scaling limits are reached, but it is incremental as it reviews existing ideas rather than proposing new methods.
The paper tackles the problem of hardware security being traditionally tied to CMOS technology by exploring how emerging technologies like spintronics and memristors can advance it, reviewing their applications and challenges.
As with most aspects of electronic systems and integrated circuits, hardware security has traditionally evolved around the dominant CMOS technology. However, with the rise of various emerging technologies, whose main purpose is to overcome the fundamental limitations for scaling and power consumption of CMOS technology, unique opportunities arise also to advance the notion of hardware security. In this paper, I first provide an overview on hardware security in general. Next, I review selected emerging technologies, namely (i) spintronics, (ii) memristors, (iii) carbon nanotubes and related transistors, (iv) nanowires and related transistors, and (v) 3D and 2.5D integration. I then discuss their application to advance hardware security and also outline related challenges.
