IRJET - Securing Communication among IoT Devices using Blockchain Proxy

This document proposes a blockchain proxy scheme to secure communication among IoT devices. The proxy requires a slim SDK on IoT devices to connect them to the blockchain while retaining full control over transactions. The proxy offloads communication tasks to save CPU and bandwidth for IoT devices. A preliminary implementation on Hyperledger Fabric shows potential savings. The proposed system uses a custom blockchain and smart contracts to analyze performance and security when IoT data is shared using this proxy scheme.
