“…The trust management plays an important role in IoDT to ensure the data trustworthiness for building high-fidelity digital twins. Representative researches in this context can be classified into two lines, i.e., quantitative trust evaluation approaches [99]- [101] and blockchain-based trustfree approaches [102]- [107]. For trust evaluations, Wang et al [100] design a quantitative trust model by integrating the direct and indirect trust evaluations.…”

“…The digital twin system is utilized to monitor and analyze traffic conditions in real-time, and the blockchain platform is used to manage trust values and offer reliable data storage. To enhance the robustness of trust management system, the blockchain-based supply chain management is also proposed in [107] for verifiable digital twins, in which each PE has an identified digital twin linked by a unique code in the blockchain.…”

By interacting, synchronizing, and cooperating with its physical counterpart in real time, digital twin is promised to promote an intelligent, predictive, and optimized modern city. Via interconnecting massive physical entities and their virtual twins with inter-twin and intra-twin communications, the Internet of digital twins (IoDT) enables free data exchange, dynamic mission cooperation, and efficient information aggregation for composite insights across vast physical/virtual entities. However, as IoDT incorporates various cutting-edge technologies to spawn the new ecology, severe known/unknown security flaws and privacy invasions of IoDT hinders its wide deployment. Besides, the intrinsic characteristics of IoDT such as decentralized structure, information-centric routing and semantic communications entail critical challenges for security service provisioning in IoDT. To this end, this paper presents an in-depth review of the IoDT with respect to system architecture, enabling technologies, and security/privacy issues. Specifically, we first explore a novel distributed IoDT architecture with cyber-physical interactions and discuss its key characteristics and communication modes. Afterward, we investigate the taxonomy of security and privacy threats in IoDT, discuss the key research challenges, and review the state-of-the-art defense approaches. Finally, we point out the new trends and open research directions related to IoDT.

Digital Twins of Supply Chains: A Systems Approach

<p>We tackle the long-standing problem of digitalisation of Supply Chains, focusing on collaboration and sharing of information. By expanding and generalising the notion of Digital Twins, we review, develop, and conceptualise the (emerging) notion of Digital Twins of Supply Chains (DTofSC). Whereas Digital Twins is now an active research area with data available from numerous industry projects, its application to Supply Chains is just emerging as a cross-discipline which, in turn, stems from decades of maturing the notion of Digital Supply Chains. The concept is still imprecise beyond key metaphors (e.g., visibility, traceability, control, etc.), but, as we conceptualise, the overall vision is to create technical and organisational mechanisms enabling any Supply Chain to be monitored and controlled from, e.g., a simple dashboard screen – taking parallels with the Internet. We perform a literature review on the intersections between Digital Supply Chains, Digital Twins, and emerging digital technologies (e.g. Blockchain). From this review, we (1) propose a synthesis systems architecture of DTofSC, (2) identify a key requirement gap (that we term addressability), and (3) to ground our contributions, apply our systems architecture to battery recycling. </p>
