Attribute-based authentication and authorization for IoT devices in 5G networks

Abstract

This poster addresses critical security vulnerabilities in 5G-integrated IoT environments by introducing an identity-token-based authentication and access control (AAC) framework. Improving on key cybersecurity concepts such as multi-factor authentication (MFA) and zero-trust architecture, this framework generates unique identity tokens using a range of attributes including IoT device metadata, user identities and real-time geolocation data. By employing behavioural attributes, the system dynamically adjusts access controls based on real-time user behaviour and environmental context addressing common and recent attacks on IoTs in a 5G environment. By optimizing signaling efficiency and minimizing computational overhead, the proposed solution enhances both network and device performance, while addressing the scalability, latency, and security challenges inherent in current 5G and IoT authentication and access control mechanisms.
