Enhanced Reliability In Iot With Sdn By Multifactor Authentication Approach

Abstract

As part of the evolving Internet of Things (IoT), security threats are becoming increasingly rampant as the number of connected devices grows, causing hackers to find their way into devices and steal sensitive data. Given the vulnerabilities of IoT devices, this paper proposes a Multi-factor Authentication (MFA) framework employing Software Defined Networking (SDN). Unlike conventional single-factor techniques, it present a method that integrates token and one-time password (OTP) authentication mechanisms under the centralized management of an SDN controller. The proposed framework minimizes unauthorized access and thus maintains network security by dynamically managing and enacting authentication rules. This paper describes, the architecture, components, and expected performance of the proposed MFA solution, paving the way for secure IoT-SDN environments and looking ahead at scalability and resilience.
