Abstract: There is exponential growth in the in the research industry of Internet of Things (IoT), but it is still vulnerable to privacy and security. Devices in the IoT having resource-constraints and decentralized topology are not capable of conventional privacy and security approaches. The paper predominantly focuses on the survey in the IoT system. Where we can see the various issues in IoT. To overcome these issues researchers, use blockchain mechanism. Due to blockchain’s popularity and success this technology is incorporated into many other industries. Blockchain is a technology that is booming since a decade. Despite various advancements in blockchain there are issues that are still present in IoT that needs to undergo improvisation. Before going to design and implement a model based on blockchain it is essential to understand the issues and challenges met by earlier research works. The paper presents study on the previous challenges and the solutions which are presented to get rid of the problems. Some of the existing problems are as follows- When the data is collected from the IoT devices and stored using blockchain still the data is under constant threat due to lack of security mechanisms relating to authentication and data privacy. Hence, providing security to blockchain becomes of utmost importance. The goal of this paper is presenting a detailed survey of security mechanisms for IoT systems. Also, this survey examines and explores why providing security to IoT devices is important. Readers can ultimately get aware of the issues that are present in the IoT systems and how they can be overcome. The study is beneficial for those who are looking forward to deploying IoT applications. They can get to know what the prerequisites are to be met for a secure IoT system.
