SDN Deployed Secure Application Design Framework for IoT Using Game Theory

The Internet of the future is software-defined networks (SDNs), which offer an evolving platform by enabling flexible reconfiguration of the network by isolating controllers and forwarding devices (switches, routers). SDN is implemented as the backbone of many real-life implications due to its capabilities of efficient traffic management, load balancing, and centralized control with dynamic reconfiguration. The Internet of Things (IoT) integrates sensors, actuators, communication systems, and cloud servers for effective and energy-efficient implementations of applications. However, ubiquitous communication systems and heterogeneous device integration make IoT systems vulnerable to end-to-end security violations. Therefore, the SDN platform and Game Theory can be used for designing efficient solutions to provide end-to-end security in the IoT environment. We introduce an SDN-deployed IoT design approach in this chapter that makes use of game-theoretic solutions. The SDN controller supports network function virtualization, which is responsible for handling different network functions in communication software and in the cloud environment of IoT. The major objective of our framework is to provide security to the hardware, software modules, the cloud environment, and the traffic flow among the different layers of the IoT. To create a framework that offers end-to-end security and accurately handles traffic among the various IoT layers, we employ a signaling game technique. The above claim is supported by a real-time case study in the robot manufacturing industry.
