How Can We Enhance Data Security in Digital Twin-Enabled IoT Networks
Apsareena Zulekha Shaik, Arnab Mitra · 2024
Digital Twin technology is best explained as the effortless assimilation of data between a physical and simulated machine in one or the other direction. Thus, the Digital Twin may facilitate the Industry 4.0 revolution through the incorporation of Internet of Things (IoT) connectivity. The increased real-time high-volume data generated by the IoT may seamlessly be handled by the Digital Twin. On the other hand, Blockchain Technology is considered an effective data security and privacy solution. For this reason, the uses of Blockchains might be realised in a variety of applications, e.g., IoT-based applications, Cryptocurrency, Insurance, eHealth, Smart City, etc. Due to its popularity, an emphasis may be observed on the advancements of existing Blockchain Technology. To support the ongoing security and privacy advancements in IoT-based networks with Digital Twin, an enhanced design in Blockchain Technology has been presented in this chapter incorporating the Elementary Cellular Automata (ECAs), as ECAs-based design supports inherent parallel computing capability, design simplicity, and low energy requirements at its physical implementation. In this chapter, the application suitability of ECAs-based design towards Blockchain Technology is initially investigated, and finally, a detailed design with ECAs toward the PageRank regular digraph (directed graph) with prime out-degrees is presented as a possible enhancement toward the Blockchain Technology. Detailed investigations further confirm the application suitability of ECAs as an energy and cost-effective model for an enhanced design in Blockchain Technology involving a cost-effective search for prime out-degrees in PageRank regular digraph towards Digital Twin enabled IoT networks.
