ABSTRACT
This chapter focuses on carbon-based designs, introduce the materials. It describes the material features that can be leveraged for security. The chapter elaborates several typical security hardware designs based on graphene/carbon nanotubes. It highlights the future research directions. In addition, different cost-efficient ways to mass-produce these carbon-based materials have been reported, such as arc discharge, liquid-phase exfoliation of graphite, and chemical vapor deposition. The electrical properties of carbon-based nanomaterials are found to be sensitive to some environmental factor changes applied on the materials. However, most of the proposed carbon-based devices so far are not specifically designed for hardware security applications. Such printable electronics exhibit high potential in hardware security applications, especially in electronic supply chain security. Many designs are proposed for logic, memory, or sensor devices, rather than from the point of view of hardware security. Such devices exhibit novel properties that are unique from existing regular complementary-metal-oxide-semiconductor devices, which makes them, promising for hardware security applications.
