摘要

智能反射面（IRS）辅助的非正交多址（NOMA）认知无线网络（crn）具有较高的通信可靠性和频谱效率。然而，由于它们向二级用户提供开放访问，它们面临着严重的安全问题。本文提出了一种全双工（FD）能量清除（ES）干扰器，在不损失能量和频谱效率的情况下保护irs辅助的NOMA crn。通过深入的保密性分析，所提出的系统模型（带FD ES干扰的irs辅助NOMA crn）的安全性大大高于两种参考模型（带FD ES干扰的irs辅助OMA crn和不带FD ES干扰的irs辅助NOMA crn）。

Secrecy analysis of IRS-assisted NOMA cognitive radio networks with full-duplex energy scavenging jammer

Intelligent reflecting surface (IRS)-assisted nonorthogonal multiple access (NOMA) cognitive radio networks (CRNs) are promising in providing high communication reliability and spectral efficiency. However, due to their open access offered to secondary users, they are facing a serious security problem against eavesdropping. This paper proposes a full-duplex (FD) energy scavenging (ES) jammer to secure IRS-assisted NOMA CRNs without losing energy and spectral efficiencies. Through thorough secrecy analysis, the security of the proposed system model (IRS-assisted NOMA CRNs with FD ES jammer) is proved to be considerably higher than two reference models (IRS-assisted orthogonal multiple access (OMA) CRNs with FD ES jammer and IRS-assisted NOMA CRNs without FD ES jammer).
