Satellite navigation systems are used in various fields requiring positioning and navigation. They transmit navigation messages including timing and orbit information through signals from satellites. However, the signals can be threatened by spoofing attacks that forge the satellite signals. To address this threat, satellite systems provide authentication services for navigation messages. In this paper, we analyze the signal authentication protocol of the Japanese satellite navigation system, QZSS. We also compare its authentication performance with those of GPS, Galileo, and BeiDou.
