Securing IoT with Digital Twins and Blockchain
Bharati B. Pannyagol, Santosh L. Deshpande · 2025
The Internet of Things (IoT) is becoming more and more connected with digital twins which are computerized copies of real assets or systems, to improve monitoring, control, and optimization capabilities across a range of disciplines. Data from physical assets is being collected in real time by IoT devices and transferred to digital twins for analysis and simulation. Blockchain technology ensures tamper-proof record keeping and fosters stakeholder confidence by securing data transfers between IoT devices and digital twins. Smart cities, transportation, healthcare, and manufacturing are just a few industries in which the suggested framework is put to use. Digital twins make supply chain security, quality control, and predictive maintenance in manufacturing possible in conjunction with IoT and blockchain. Patient monitoring systems in the healthcare industry use this connection to guarantee data privacy, integrity, and legal compliance. Through real-time monitoring of vehicles and infrastructure assets, transportation networks may achieve increased security and efficiency. The framework is used by smart cities to enhance energy management, urban planning, and citizen participation while preserving data security and privacy. Blockchain technology uses cryptographic hashing, smart contracts, and decentralized consensus. Smart contracts automate tasks, decentralized consensus methods build trust in the dearth of centralized authorities, and cryptographic hashing assures data confidentiality and integrity. Understanding its architecture thoroughly is essential to maximizing its potential and fostering creativity in the digital age, applications, and essential components in integrating digital twin with IoT and blockchain. This chapter offers an in-depth analysis of architecture, uses, and essential elements, making it an invaluable tool for comprehending the technology&s;s potential to transform several industries and spur creativity in the digital era.
