Abstract
The Internet of Things (IoT) connects every device possessing some element of computer technology or a digital interface. These devices constitute a global interconnected network that bridges the gap between the physical and virtual worlds. Today, there are two major applications for IoT—Consumer Internet of Things (CIoT), concerned with interactions between consumers and IoT devices, and industrial Internet of Things (IIoT), focussed on the utilisation of IoT for designing industrial systems. With the proliferation of IoT devices for myriad applications, it is becoming increasingly important to investigate and understand the factors essential to securing them against external threats. These factors directly influence the design, functionality and the standards and regulations for IoT devices. This paper defines the trust and resilience of IoT systems and provides unambiguous definitions for key factors (security, privacy, safety, recoverability, reliability and scalability) that directly influence the trust and resilience of IoT systems. Based on the results of a survey conducted amongst IoT consumers and experts, this paper ranks each of these factors in the order of their importance in determining the trust and resilience of CIoT and IIoT systems. These rankings are generated using the analytic hierarchy process (AHP) and a pairwise analysis of the collected data.KeywordsInternet of thingsTrust and resilienceSecurity
