A Secure Software Defined Networking based Framework for IoT Networks

Ambili K N and Jimmy Jose

Abstract: The connectivity is increasing in the world with the increased usage of IoT (Internet of Things) devices. To this end, amount of data that needs to be stored and retrieved securely has increased tremendously, but the IoT devices have a small amount of memory and computation capacity. Consequently, a storage area with a large amount of secured storage space is needed. Software-defined Networking (SDN) is an emerging network technology which implements a new paradigm of insecure applications and IoT services. To build a heterogeneous secure network, we introduced SDN controller broadcast encryption using the Open Network Operating System integrated with network switches and SDN Controllers. In this paper, we propose a secured data sharing system in IoT devices in which the IoT devices are connected to an SDN controller and data from the IoT device is encrypted. Only the corresponding authorized switch receives the data and knows the exact key to decrypt the ciphertext, so the data is stored and retrieved securely. In this system, we use Wheatstone algorithm to encrypt the data from the IoT devices. The usage of this algorithm helps to avoid botnet attacks and other types of attacks on the data. The proposed system established new forwarding paths through controller and it communicated with authorized switches for secure data transmissions. We analyzed the performance of our proposed algorithm using OMNeT++ to simulate our entire scenario and confirmed that the algorithm is efficient and secure in IoT applications. This extends the security features of IoT applications.
