Abstract

This letter investigates the physical-layer security of multi-user networks and proposes a secure and interference-free transmission scheme. The scheme constructs the transmitted signals of different users by using the characteristics of the Hadamard matrix, and injects self-interference and artificial noise that can be eliminated by legitimate users but not by eavesdroppers, thereby significantly improving security. We analyze the asymptotic security performance and obtain the secrecy outage probability when the number of users is large enough. Finally, simulation results exhibit the security performance of the proposed scheme.

期刊介绍： The IEEE Communications Letters publishes short papers in a rapid publication cycle on advances in the state-of-the-art of communication over different media and channels including wire, underground, waveguide, optical fiber, and storage channels. Both theoretical contributions (including new techniques, concepts, and analyses) and practical contributions (including system experiments and prototypes, and new applications) are encouraged. This journal focuses on the physical layer and the link layer of communication systems.
