The BeiDou system (BDS) plays a significant role in people’s lives, but its security is easily affected by spoofing attacks. The radio determination satellite service (RDSS) is a special service of BDS that provides two-way communication, positioning, and timing services independently of the traditional radio navigation satellite service (RNSS). It can additionally be combined with RNSS to provide a comprehensive RDSS (CRDSS) service. In RDSS, after receiving a signal from the master station, the user needs to send a response signal back to the master station through a satellite. Therefore, the RDSS signal is difficult to spoof. In this study, based on the security feature of RDSS signals, an anti-spoofing method based on CRDSS is proposed to detect and mitigate spoofing attacks, verifying the advantages of the BeiDou system over other satellite navigation systems.

基于综合无线电确定卫星业务的北斗反欺骗技术研究

北斗系统（BDS）在人们的生活中起着重要作用，但是其安全性很容易受到欺骗攻击的影响。无线电确定卫星服务（RDSS）是BDS的一项特殊服务，它独立于传统的无线电导航卫星服务（RNSS）提供双向通信，定位和定时服务。它可以与RNSS结合使用，以提供全面的RDSS（CRDSS）服务。在RDSS中，用户从主站接收到信号后，需要通过卫星将响应信号发送回主站。因此，很难欺骗RDSS信号。本研究基于RDSS信号的安全特性，提出了一种基于CRDSS的反欺骗方法来检测和减轻欺骗攻击，
