Establishing Trustworthy Relationships in Multiparty Industrial Internet of Things Applications

The uptake of smart devices in the manufacturing industry is accelerating as technological advancements enable hardware to become cheaper and more accessible. A primary concern for manufacturing companies, as well as those in the associated logistics supply chains, is how to establish trust between smart devices, such that the delegation of transactional responsibility and accountability, which is required for Industry 4.0, can be facilitated in a secure and sustainable manner. Trustworthy systems enable enhanced manufacturing operations to occur securely, while also providing a robust audit trail of digital evidence to support any future investigations into allegations of system breaches. This chapter examines a specific type of trust relationship that regularly occurs in supply chains—multiparty authentication—and proposes a framework that encompasses both the human and technical factors that must be considered to engender trustworthy relationships between IIoT devices and organisational operations technology.
