Rapid development of internet and communication throughout the world has made IoT one of the key components of fourth industrial revolution. IoT has its impact on various aspects of our life and has remarkable contributions to world economics. Integrated with different technologies, IoT has been expanded to many more applications thus making direct interaction with our personal and corporate life. Security of these devices has been a major issue. But problems arise with on-demand security solution as devices are provided with low processing and energy resources. Heavy and expensive systems cannot be applied to IoT devices. Addressing these problems, in this paper we propose a novel blockchain based framework for IoT device data sharing and communication. We implemented a prototype of our proposed framework using Hyperledger Fabric and evaluated its performance. We show that our proposed solution is efficient for IoT devices and different security requirements such as confidentiality, availability and integrity of data are met.
