Comparative Analysis of IoT Architectures: Cloud vs. Blockchain for Security, Scalability, and Privacy concerns
Keywords:
Blockchain, Centralized, Cloud, Decentralized, IoT securityAbstract
In this paper we draw a comparison for IoT architecture, when it gets implemented through Cloud and through Blockchain. Both have different perspectives of dealing with IoT devices, strength and limitation both are discussed in this paper. This paper showcases how centralized structure is used for IoT with Cloud which has a great scalability, suitable for smart rooms, smart medical systems, smart grocery shops, etc. And also shows the drawbacks like security, privacy as the data gets stored in centralized architecture. Whereas another aspect of this paper discusses IoT with Blockchain, which has decentralized architecture and enhances the security, integrity, storage but this also comes with some drawback like scalability, latency. The study made in paper shows case requirements describing which architecture is better for which case.
