Abstract

The unanticipated advancement of the Internet of Things (IoT) has provided worries concerning secrecy of evidence, user’s exclusivity, and truth of devices inhibited. This paper provides a human-centric, blockchain-sharded MQTT solution to ensure security of human IoT communications and maintain its productivity and user control. In contrast to the deterministic MQTT solution that relies on resource-limited Transport Layer Security (TLS), the intended solution relies on blockchain sharding and user-controllable intelligent contracts to achieve decentralized control over contacts and scalability. The response allows users to sum up and approximate data distribution authorisation and entails evidence-of-access to traceability and accountability in information dispensation. Concert improvements, up to 80 percent bandwidth reduction of conventional protocols, more than 60 percent CPU and memory enhances and reduction, and half of the end-to-end latency of the TLS-based and blockchain-based outcomes are established through experimental results of variuos MQTT brokers, such as HiveMQ, Mosquitto, EMQX, and Eclipse. To add to the concert perks, this study will contribute to the existing discussion on the ethics of the IoT schemes because it will enhance data control and autonomy without compromising efficiency. The solution is expected to provide a scalable, secure, and responsibility-based platform of the next-generation IoT schemes.
