Internet of things(IoT) is a network that consisting of billions of devices, which provides an opportunity to an intruder to manipulate the IoT system on a large scale. It can be described as, the connection of things or devices across the internet to deliver upon an assigned function. This mainly comes in the form of devices sending or receiving data. At the hardware layer, an attacker gets access to the IoT hardware and retrieves the keys or security parameters stored inside the IoT device. The attacker can recreate a duplicate or virtual IoT device using the stolen security parameters. The duplicate IoT device can upload false data to the server and retrieve secure information about the user from the server or the network to which the IoT device is connected. The aim of this project is to provide a two-level and session-based secure data communication. To provide a secure data communication between IOT devices and cloud and between different IOT devices by creating permission based block chain and hashing the data which is being shared by different IOT devices. In this application we propose a novel cryptographic ledger based framework for IoT device data sharing and communication and planning to implement the prototype of our proposed framework using Hyper Ledger Fabric and evaluate its performance.
