卫星导航接收机欺骗攻击及防护综述

本文主要研究卫星导航欺骗干扰技术与欺骗防护技术，首先介绍欺骗干扰的生成方式、欺骗干扰实施策略与播发策略，并从欺骗威胁、实现难度、防护难度等多方面给出现有欺骗技术的对比分析。其次从信号体制、终端处理技术、辅助信息校验技术等三个层面介绍现有欺骗防护技术，并从欺骗适应性、实现需求、实现难度、实现效果等几方面给出防护技术对比分析。在此基础上，研究在面对不同欺骗攻击时接收机的欺骗防护框架，对于评估导航接收机的防护能力有借鉴意义。

Analysis on Spoofing Attack and Anti-spoofing Framework of GNSS Receiver

This paper focuses on the spoofing and anti-spoofing technology and protection of GNSS receiver. Firstly, the signal generation and spoofing implementation strategies are introduced, and several aspects such as spoofing threat implementation difficulty and protection difficulty are compared and analyzed. Secondly, an analysis of anti-spoofing technologies is discussed from three aspects: signal system, receiver signal processing technology and auxiliary information verification technology. A comparative analysis of anti-spoofing technologies is provided from the aspects of spoofing adaptability, implementation requirements, implementation difficulty, and effectiveness. Based on these, the anti-spoofing framework of GNSS receiver is proposed to deal with different spoofing attacks, which has significant reference for evaluating the spoofing procetion ability of GNSS receivers.
