The Internet of Things refers to the ever-growing network of physical objects that feature an IP address for internet connectivity, and the communication that occurs between these objects and other Internet-enabled devices and systems. IoT can connect a variety of physical objects, to reach common goals. In some of the IoT applications data can be stored in distributed hash tables while the DHTs stored address can be stored in Blockchain. IoT devices have low computational powers coming and they are not capable of conducting complex computations. In a traditional cloud-based IoT structure, a centralized cloud server collects and controls all the data, which brings two drawbacks: The cloud server needs very high storage capacity to store the IoT data and Sensitive data can be easily leaked from the server. The Development of the internet of things has made extraordinary progress in recent years. Storing and protecting this huge volume of IoT data has become a significant issue. Traditionally, cloud based IoT structure were used but they lead to high computation and storage demands on the cloud servers. Due to centralized servers, there were many trust issues. To solve these problems, we have proposed a distributed data storage scheme employing Blockchain and certificate less cryptography. Blockchain serves as an unchangeable ledger that allows transactions take place in a Decentralized manner. To the best of our knowledge, this is the first work designing a secure and responsible IoT storage system using Blockchain.
