Performance Analysis of PLS key generation-based Secure NOMA-enabled IoT Networks in the presence of Untrusted Users

Abstract

In Internet of Things (IoT), a massive amount of sensitive data is generated and transmitted by IoT devices. Security risks represent a major concern in IoT, especially when using innovative techniques such as Non-Orthogonal Multiple Access (NOMA) technique, where users can access other users' data. In fact, in NOMA-based IoT systems, communication is not only threatened by external eavesdroppers, but also by untrusted internal users. Therefore, it is necessary to adopt an encryption technique that guarantees IoT system communications. This paper presents a comparative study of secret key generation, where performance analysis of secure NOMA-enabled IoT network in the presence of untrusted users is detailed using different PLS key generation schemes. 2021 IEEE.
