Secure Transmission of 5G Beyond Networks for SWIPT NOMA Assisted by LIS

The paper addresses security concerns in large intelligent meta-surface assisted non-orthogonal multiple access (LIS-NOMA) infrastructures for simultaneous wireless information and power transfer (SWIPT) in the uplink channel. The primary objective is to ensure the privacy and security of the available bandwidth, thus preventing unauthorized access. By proposing the integration of SWIPT and NOMA, the paper provides a guarantee to achieve the objective. The suggested approach utilizes software-defined radio (SDR) to maximize secrecy probability and enhance signal security performance at the base station. Furthermore, the paper tackles the challenge of maintaining quality of service for authorized users while ensuring their safety. The proposed solution showcases the promising potential for enhancing security in SWIPT-NOMA infrastructure.
