Blockchain for Internet of Things: A Survey
Hong-Ning Dai, Zibin Zheng, Yan Zhang
This survey provides an in-depth exploration of the challenges and opportunities associated with combining blockchain technology with the Internet of Things (IoT). The authors identify the core limitations of existing IoT architectures, such as centralized management, single points of failure, and inherent security vulnerabilities. By examining current blockchain-IoT integration models, the paper highlights how decentralized consensus can enable secure device communication and data integrity. It categorizes existing research into distinct areas, including resource management, device authentication, and secure data storage, while meticulously detailing the constraints imposed by hardware limitations in IoT environments. The authors present a comparative study of various blockchain platforms and consensus mechanisms, evaluating their applicability to heterogeneous IoT networks. The paper concludes by defining open challenges, such as interoperability and the need for standardized frameworks, while offering a clear roadmap for future interdisciplinary research in the field of IoT security and performance.
A survey on internet of things security: Requirements, challenges, and solutions
Hamed HaddadPajouh, Ali Dehghantanha, Reza M. Parizi, Mohammed Aledhari, Hadis Karimipour
This survey paper evaluates the security landscape of the Internet of Things (IoT), mapping out the complex requirements and potential solutions necessary to protect modern connected ecosystems. The authors conduct a comprehensive review of existing attack surfaces, ranging from physical device tampering to network-level threats, and analyze the efficacy of current defensive strategies. A significant portion of the analysis is dedicated to the role of blockchain technology and other cryptographic primitives in providing immutable audit trails and decentralized trust mechanisms. The paper highlights the disconnect between high security requirements and the limited processing power of IoT devices, proposing a taxonomy of security solutions that balance protection with operational efficiency. By investigating the intersection of IoT with emerging paradigms like edge computing and cloud integration, the authors provide a rigorous foundation for researchers and practitioners to design more robust, resilient, and secure IoT architectures.
Blockchain and the Future of the Internet: A Comprehensive Review
S. M. M. Rahman, M. S. Islam, M. A. R. Khan
This comprehensive review analyzes the symbiotic relationship between blockchain technology and the evolution of the Internet. The paper examines the history of the Internet's centralized growth and positions blockchain as a corrective measure to address privacy, security, and data ownership concerns. The authors categorize applications across identity management, domain naming systems, and decentralized web storage, illustrating how cryptographically secured ledgers empower users to reclaim ownership of their digital footprint. By synthesizing existing literature, the review highlights the emergence of decentralized applications (dApps) as the vanguard of this new paradigm. Furthermore, it addresses the energy consumption issues associated with traditional consensus mechanisms, suggesting that shift towards Proof-of-Stake (PoS) and energy-efficient algorithms is critical for long-term viability. The paper provides an academic analysis of how blockchain can facilitate a user-centric web experience while maintaining functional performance and scalability standards.
