A Novel Approach to Solve Security and Privacy Issues for IoT Applications Using Blockchain

Internet of Things(IoT) has emerge as a revolution in last decade. The IoT deals with lots of smart things interconnected with each others. The smart things are used to monitor, read, access the different smart applications environments. An IoT application has different challenges such as bandwidth/traffic issue, scalability challenges, device mobility, along with security and privacy issues. To make use of IoT in real-life application confidentiality, integrity, authentication, authorization, trust, verification, information storage, and management, availability challenges need to be addressed. In this work, initially, authors have explained the security and privacy challenges that currently exist in IoT applications. Following which, authors have identified that Blockchain Technology addressed the security and privacy issue in some papers. Blockchain technology being distributed architecture is secure and tamper-proof explained. Finally, paper concluded that the distributed Blockchain technique has the potential to provide a solution to the existing security and privacy challenges of IoT application.
