AB  - Nonorthogonal multiple access (NOMA) is a relevant technology for realizing the 
      primary goals of next-generation wireless networks, such as high connectivity and 
      stability. Because a rising number of users are becoming connected, user data 
      security has become a critical issue. Many chaotic communication systems have 
      been established to address this important issue via exhibition of affordable 
      physical-layer-security solutions. In this study, we propose a chaotic downlink 
      NOMA (C-DL-NOMA) system over the additive white Gaussian noise and 
      Rayleigh-fading channels to enhance the security of the DL-NOMA system. The 
      proposed algorithm is based on a coherent analog modulation technique that 
      combines various chaotic maps for chaotic masking of encrypted data. On the 
      transmitter, chaotic encryption was used for transmitted data with fixed 
      power-allocation-level control, whereas on the receiver, successive 
      interference-cancellation demodulation was utilized to detect multiple users, 
      after which chaotic decryption was performed. Simulation results were evaluated 
      based on security analyses, such as statistical analysis (histogram and 
      correlation analyses and information entropy), bit-error-rate performance, and 
      achievable-data-rate performance. According to these security analyses and 
      numerical results, the proposed C-DL-NOMA system outperformed traditional 
      unencrypted NOMA systems.
