摘　　要：物联网安全通信传统上依赖密码学技术,但面对物理层攻击时保护力度不足。为此,研究提出了人工噪声辅助的安全通信方法。该方法设计预编码矩阵缓解多用户干扰,进行信号预处理,并建立安全通信接收模型。通过引入人工噪声技术,设计权重向量平衡对合法用户和窃听者的干扰效果,使合法用户利用信道优势恢复信号,确保安全通信。实验表明,该方法在不同信噪比和实验次数下性能卓越,显著提高了传输速率,大幅降低了丢包率,有效提升了物联网通信的安全性和效率。Traditionally,secure communication in the Internet of Things has relied on cryptographic techniques,but there is insufficient protection against physical layer attacks.Therefore,a secure communication method assisted by artificial noise has been proposed in the study.This method designs a precoding matrix to alleviate multi-user interference,performs signal preprocessing,and establishes a secure communication receiving model.By introducing artificial noise technology and designing weight vector balance to mitigate interference effects on legitimate users and eavesdroppers,legitimate users can utilize channel advantages to recover signals and ensure secure communication.Experiments have shown that this method performs excellently under different signal-to-noise ratios and experimental times,significantly improving transmission rates,significantly reducing packet loss rates,and effectively enhancing the security and efficiency of IoT communication.
