Poster: Attribute Based Access Control for IoT Devices in 5G Networks

Abstract

The deployment of 5G technology has the potential to usher in a new era for the internet of things (IoT). The introduction of new use cases, such as massive machine-type communications (mMTC), referring to a large number of IoT devices, resulting in the increasing importance of 5G as the basic communication infrastructure for IoT. However, the increasing connectivity of IoT devices coincides with a number of risks to security. Many IoT sensors have limited resources and, therefore, cannot perform the complex security measures required to protect them from attacks and data loss. Furthermore, IoT networks are very scattered, distributed and dynamic, so decentralised security measures are required. To address these challenges, this poster proposes the integration of attribute-based access control (ABAC) into the 5G service-based architecture. This approach aims to prevent unauthorized access to IoT devices at the network level, thereby alleviating the computational burden on resource-constrained IoT devices. By implementing ABAC, the proposed solution offers a more efficient method for managing access control within the IoT landscape in the context of 5G networks.
