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.

无线多用户网络中的安全无干扰传输

这封信研究了多用户网络的物理层安全性，并提出了一种安全、无干扰的传输方案。该方案利用 Hadamard 矩阵的特性构建不同用户的传输信号，并注入合法用户可以消除而窃听者无法消除的自干扰和人工噪声，从而显著提高了安全性。我们分析了渐进安全性能，并得出了当用户数量足够大时的失密概率。最后，仿真结果表明了所提方案的安全性能。

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.
