چکیده :

Abstract—NOMA systems are considered as one of the key technologies in 5G communication systems due to their high data rate and large capacity. However, by increasing the number of users, the issue of secure data transmission in these systems becomes very important. In general, security considered as a concept that should be evaluated separately from the radio transmission aspects of wireless systems. However, with the emergence of new network architectures, interest in the physical potential of the wireless channel and its features for providing secure communications has increased. In this paper, we aim to evaluate the physical layer security (PLS) from the perspective of information theory for eavesdropping channels in NOMA systems using a method based on chaos theory. Then we derive an approximate closed-form for secrecy outage probability (SOP) in four interception scenarios.
