A multi-layer security model for 5g-enabled industrial internet of things

Abstract

This article considers the need for secure communications between Industrial Internet of Things (IIoT) devices that operate in 5G-enabled environments. 5G networks enable greater data throughput and lower latency, which presents new opportunities for the secure authentication of business transactions between IoT hardware. We propose an approach to developing a flexible and secure model for IIoT components in 5G environments. Using the National Institute of Standards and Technology (NIST) seven layer model of cloud computing, in conjunction with Physically Unclonable Function (PUF) hardware provided via FPGAs, we demonstrate algorithms that replicate common authorisation challenges in 5G enabled IoT scenarios.
