中间欺骗可以影响大多数现有的全球导航卫星系统（GNSS）接收器，因此低成本检测这种欺骗对于保护关键安全和金融应用中使用的GNSS接收器的可靠性非常重要。本文提出了两种分析中间欺骗攻击者攻击的策略，以识别中间欺骗攻击者的弱点。在分析的基础上，提出了一种码与载波相位一致性检测方法，仿真结果表明，该方法可以在发生欺骗时提示接收方。这种方法可以被大多数接收器使用，价格低廉，只需要一个小的软件升级。
Intermediate spoofing can impact most off-the-shelf Global Navigation Satellite Systems (GNSS) receivers, therefore low cost detection of such spoofing is very important to protect the reliability of the GNSS receivers used in critical safety and financial applications. This paper presents two strategies to analyze attacks by intermediate spoofing attackers to identify the weaknesses of such attacks. The analyses lead to a code and carrier phase consistency detection method with simulation results showing that this method can indicate the receiver when spoofing has occurred. The method can be used by most receivers, is inexpensive, and requires only a small software upgrade.
