SHSec: SDN based Secure Smart Home Network Architecture for Internet of Things

To address the challenges of flexible device utilization, heterogeneous device interoperability, and security enhancement in smart homes, this paper proposes a new architecture for the software defined network to realize secure smart home environment (SHSec). SHSec concentrates on the capabilities required to deliver a flexible generic platform and the modularity of open-source service creation components for a user-friendly smart home by adopting the traditional software-defined network concept. It offers an infrastructure that is agile, modular and, most importantly, secure. To avoid many manual reviews and recommendations by administrators, security should automatically adapt to any threat in the immediate environment. We simulated the proposed model to test network performance and feasibility during link failures and switching in a normal environment. We also evaluated the performance of our proposed model based on various metric parameters. The results of the simulation show that SHSec management is able to detect and mitigate attacks, and can also be used to secure the system, ensure user security, and improve the heterogeneous local network. The proposed model achieves an accuracy of 89.9% and a sensitivity of 91.1% while predicting malicious events.
