Positioning signal deception identification method, device and equipment and storage medium

Abstract

The invention relates to a positioning signal deception identification method and device, equipment and a storage medium. The method comprises the following steps: acquiring a positioning signal, wherein the positioning signal comprises three-dimensional coordinate information; determining first feature information corresponding to the three-dimensional coordinate information based on the high-precision map data; acquiring environment sensing data; obtaining the environment sensing data by sensing the surrounding environment through sensing equipment; determining second feature information based on the environment perception data; determining a matching degree value between the first feature information and the second feature information; and if the matching degree value is less than or equal to a preset matching degree value, determining that the positioning signal is a deception signal. Therefore, the monitoring and identification problems of GNSS positioning signal spoofing attacks can be solved, so that the driving safety of the vehicle can be improved.

Description

technical field [0001] The present application relates to the technical field of vehicle information security, in particular to a method, device, device and storage medium for identifying fraudulent positioning signals. Background technique [0002] With the development of Global Navigation Satellite System (GNSS), satellite navigation technology has been widely used in various industries and supports many application systems. It can provide services such as precise location information and time synchronization. Its applications in financial transaction records, vehicle positioning, military and aerospace all show the strong application value of GNSS, so people are more and more concerned about the received GNSS signals accuracy and reliability. [0003] However, with the rapid development of science and technology, the vulnerability of GNSS positioning system to interference and spoofing is gradually exposed. The existing GNSS positioning system is vulnerable to various fo...
