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 diffi-culty 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,implemen-tation 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.
