BLOCKCHAIN-ENABLED SECURE DATA SHARING PROTOCOL FOR SMART CITIES

International Journal of Computer Science (IJCS) Published by SK Research Group of Companies (SKRGC)

Abstract

The possibility of availability of the Blockchain technology to the smart cities has emerged with a powerful mechanism of secure, transparent and an efficient exchange of information. With the increased usage of Internet of Things (IoT) gadgets, the smart cities are growing into huge collections of sensitive data that ought to be guarded against unauthorized access, tampering, and infiltration. A secure data sharing protocol based on blockchain is proposed in this paper particularly to smart cities. The proposed protocol implements decentralized ledger and secure means of data storage and sharing among the IoT devices, the city infrastructure, and individuals in the present era. In the present paper, encryption, access control, real-time validation of the transaction are identified as the key features of the protocol, which solves the challenges of scalability, security, and trust in the context of smart cities. This simulation model of the actual sharing of data situations at smart cities brings out the efficiency of their own protocol. The results show that the protocol enhances the integrity of the data, small latency and overall resource-efficient utilization in large scale IoT networks. Further, the paper expounds on how the protocol offered can have the opportunity to make future smart city initiatives including cars without drivers, managed energy and health networks in the urban living environment. The findings suggest that data privacy and commitment in smart cities can be transformed drastically using the solutions based on blockchain technology and serve as the strong foundation of future city innovations.
