IoT Blockchain Platform

The project a security architecture model which integrates a private blockchain network , fog & Edge computing, and defined software networks for the Internet of Things.

In our project is to integrate blockchain app with IoT fog computing platform through SDN-based architectures and to apply a public encryption technique to secure cloud storage and using context-aware attributes-based CP-ABE for data privacy policy . in addition, Authentication is done via a remote Proxy/Fog, which is a part of the Cloud through blockchain . It receives the user’s authentication & encrypt the data. Also, we plan to integrate an End point detection & response system using various techniques to prevent the injection of fraudulent IoT data into the smart IoTs.
These architectures are divided into the following:

• Edge: composed of devices responsible for ensuring access control, secure data communication, and the application of security rules for managing local area networks.
• Fog: composed of SDN controllers responsible for detecting threats, defining the appropriate mitigation policies, and sending them to the devices at the edge layer. In addition, they periodically report the records of events that have occurred to the cloud layer.
• Cloud: contains a holistic view of all managed IoT domains and is, therefore, able to identify attack patterns from different domains. In this way, mitigation policies at the global level can be established.
• IoT devices & IoT gateway.
