    Abstract
    Internet of Things (IoT) systems have been playing a significant role in improving the quality of various applications and services. With the expansion increase of loT devices and users, different Multiple Access (MA) techniques have been proposed to overcome the spectrum scarcity and the high latency. However, in MA-based loT systems, communication is not only threatened by external eavesdroppers but also by untrusted internal users. Therefore, proposing secured MA-based loT systems is of high importance. This paper proposes a hybrid Non Orthogonal Multiple Access (NOMA) I Orthogonal Multiple Access (OMA)-based loT system to improve the data transmission security. The proposed scheme exploits the advantages of the two different MA techniques as well as the Physical Layer Security (PLS). We first describe the system model and then we detail the proposed scheme and the relevant performance analysis. Finally, our simulation results verify the accuracy of the derived expressions and evaluate the advantage of the proposed scheme, when compared to the pure NOMA and pure OMA-based loT systems.
