Blockchain‐Based Cyber Physical Trust Systems

Cyber Physical Trust Systems (CPTS) are Cyber Physical Systems and Internet of Things enriched with trust as an explicit, measurable, testable system component. In this chapter, we propose to use blockchain technology as the trust enabling system component for CPTS. Our proposed approach shows that a blockchain based CPTS achieves the security properties of data authenticity, identity and integrity. We describe results of a testbed which implements a blockchain based CPTS for physical asset management. extend the testbed into a generic application for supporting Cyber Physical Trust Systems, and conduct in depth performance analysis ranging from theoretical ones based on theoretical performance assumptions of blockchain technology, to practical ones in relation to an enhanced testbed implementation. We will also explore other application domains, in which Cyber Physical Trust Systems can be applied.
