TL;DR: This paper describes how semantic digital twins and blockchain can be used to provide security and scalability to constrained IoT devices.
Abstract: Digital twins are largely used to enable the Industry 4.0 and other Internet of Things applications. This approach has been built to support the product entire lifecycle and has advantages such as interoperability, availability, and simulation capabilities. If integrated with distributed ledger technologies, such as blockchains, digital twins can augment their applications, becoming an anchor of trust for constrained IoT devices. This paper describes the Constrained Devices Management Platform, a BT research system designed to enhance the security of IoT systems, with an especial focus on data provenance, immutability, and integrity. Lastly, the paper describes how semantics can enhance the CDMP capabilities through interoperability.
