Blockchain-based Web of Things Security: Advances, Challenges, and Solutions

“Blockchain-based Web of Things Security: Advances, Challenges, and Solutions” offers a concise yet comprehensive exploration of how blockchain technologies can enhance the security and trustworthiness of the Web of Things (WoT). It bridges theoretical foundations with applied research to guide academics, engineers, and decision-makers in deploying decentralized security solutions for interconnected environments. Starting with the evolution from IoT to WoT, the book outlines the interoperability and security challenges of integrating billions of devices into the web. It then introduces blockchain as a key enabler of trust, transparency, and resilience, covering its cryptographic principles, consensus models, and smart contract capabilities. The chapters delve into blockchain-based frameworks for WoT security, including decentralized identity management, secure key revocation, and distributed SSO systems. Sector-specific use cases such as intelligent transport and industrial automation demonstrate how blockchain mitigates vulnerabilities and ensures data integrity. The book also explores the synergy between blockchain and emerging technologies like edge computing, AI, and digital twins, with a focus on real-time anomaly detection and threat mitigation. Practical insights, architectural templates, and regulatory perspectives round out this volume, making it a valuable reference for building secure, scalable, and interoperable WoT ecosystems.
