中文摘要	在全球导航卫星系统的安全性能准确评估问题的研究中,预测及评估欺骗对接收机的影响尤为重要。在导航对抗环境下,对接收机的定位结果进行控制是转发式欺骗攻击的核心目标。由于接收机既接收处理卫星播发的真实信号又接收处理欺骗信号,定位结果难以预测,使得欺骗攻击的效果难以预测,进而严重影响欺骗攻击的性能。针对上述问题,提出了一种用于预测及评估转发式欺骗攻击性能的方法——位置矢量分析法。根据当前卫星星座、接收机真实位置以及欺骗机希望目标接收机出现的定位结果,首先通过建立线性化测量方程,分析各通道欺骗信号对接收机的影响,然后综合评估所引起的接收机位置矢量变化,进而给出转发式欺骗对接收机定位结果的影响。仿真结果表明,该方法能有效预测转发式欺骗对目标接收机定位结果的影响,可正确评估转发式欺骗攻击的性能,为全球导航卫星系统的安全性能评估提供了理论依据。; Predicting the effects and evaluating the performance of spoofing to receiver is particularly important to evaluate security of global navigation satellite system(GNSS).In GNSS navigation confrontation,manipulating a receiver's PVT solution is one of the core objectives of spoofing attacks.Since a GNSS receiver is more likely to receive spoofing and legitimate signals,its PVT solutions are highly unpredictable.Thus,it is quite difficult to evaluate the performance of replay attacks.To this end,a position vector analysis method(PVAM) was proposed to forecast the impact and evaluate the performance of replay attacks.According to current GNSS constellation,the actual position of the GNSS receiver and the position were expected by a spoofer,which launches replay attacks and broadcasts spoofing signals.The method builds a set of linear measurement equations to analyze the influence of spoofing signals of each channel on receiver.Then,based on the influences,the influence of spoofing signals on the receiver's position vector and PVT solutions were investigated.Theoretical and simulation results demonstrate that the method is effective to predict the influence of replay attack on receivers.The proposed method is of great significance to predict the effects of replay attacks on GNSS receivers,and evaluate the performance of a replay attacks.These conclusions are significant for evaluating the security performance of GNSS.
