Securing the Connected World: Fast and Byzantine Fault Tolerant Protocols for IoT, Edge, and Cloud Systems

Abstract

The rapid advancement of technology has brought about profound changes in various spheres of our society. Among these improvements, the Internet of Things (IoT) stands out as a transformative force, revolutionizing visibility across diverse domains. By furnishing real-time data and insights, IoT empowers businesses to refine their operations and significantly enhance overall efficiency. However, the decentralized nature of IoT architecture presents a substantial challenge in terms of security. As technology proliferates, security emerges as a paramount concern, particularly in safeguarding IoT devices and the data they generate against unauthorized access, data breaches, and potential harm. Simultaneously, the imperative for real-time data streaming underscores the need for a rapid dissemination protocol as a fundamental requirement. Our proposed solution adeptly addresses both of these critical aspects by integrating BDLS, a promising Byzantine Fault Tolerance (BFT) protocol, with Hyperledger Fabric for IoT devices. This integration not only enhances security but also ensures the rapid and secure dissemination of data. Through rigorous evaluation, our study demonstrates the outstanding performance of BDLS Fabric integration in terms of throughput (TPS), surpassing CFT-type protocols and numerous other proposed solutions utilizing PBFT, thereby reinforcing the importance of security in IoT deployments. Moreover, by securing the edge servers and the cloud replica using Hyperledger Fabric-BDLS integration, our solution fortifies the IoT ecosystem against potential threats, establishing a robust foundation for future innovations in distributed ledger technology.
