Abstract: Disclosed are a secure communication device and a secure communication method using an artificial noise scheme. The secure communication method between a multi-antenna legal transmission device and a multi-antenna legal reception device includes determining a power allocation ratio for a system parameter, by the legal reception device, generating a transmission signal including a secret information message based on the determined power allocation ratio and artificial noise, and transmitting the generated transmission signal to the legal reception device.

Abstract: A learning method for a two-stage deep learning base secure precoder for information and an artificial noise signal in a non-orthogonal multiple access (NOMA) system is provided. The learning method for designing the two-stage deep learning based secure precoder for the information and the artificial noise signal in the NOMA system may include performing pre-training for downlink NOMA before information transmission to maximize a sum secrecy rate while ensuring secrecy rates of respective legitimate users, each having a single antenna (secrecy fairness), and performing post-training by fine tuning a neural network learned by the pre-training using unsupervised learning.
