A security framework for IOT devices against wireless threats

Everyday number of smart devices or IOT devices either it be a smart phone, tablet, smart home device or any wearable technology are being connected to the internet. These IOT devices have become an essential part of our everyday life. We use them in many forms without being aware that we have started depending on them like for security purpose we use security systems in our house, or the smarts locks on our doors to keep our self-safe from the moon lighters. But do we really consider our security that seriously. Today IOT device security has become one of the major concern of the IT Industry. In this paper, we are using the block chain technique to develop a framework for security and management of data on the internet. We have developed a framework which shows how smart devices communicate with each other with block chain posing as the backbone. The framework serves as a scalable and robust solution, in order to address identity and security concerns of IOT. The proposed framework is further compared to existing models.
