Embodiment 1

[0057] This embodiment provides a GPS spoofing detection method based on RSSI, such as figure 1 shown, including the following steps:

[0058] S101. Receive a GPS signal, where the GPS signal includes received actual signal strength RSSI and first latitude and longitude information;

[0059] S102. Calculate and obtain the predicted signal strength RSSI-infer according to the first latitude and longitude information of the received GPS signal;

[0060] S103. Calculate the similarity DTW between the predicted signal strength RSSI-infer and the actual signal strength RSSI;

[0061] S104. Compare the calculated similarity with a preset similarity threshold to determine whether GPS spoofing occurs.

[0062] RSSI (Received Signal Strength Indication), which indicates the signal strength received by the signal receiving end, is an optional part of the wireless transmission layer, so it is a physical quantity and will not be subject to spoofing attacks. The present invention uses t...

Embodiment 2

[0096] This embodiment provides a GPS spoofing detection device based on RSSI, such as Figure 5 shown, including:

[0097] A receiving unit, configured to receive a GPS signal, the GPS signal including received actual signal strength RSSI and first latitude and longitude information;

[0098] The first calculation unit is used to calculate and obtain the predicted signal strength RSSI-infer according to the first latitude and longitude information of the received GPS signal;

[0099] The second calculation unit is used to calculate the similarity DTW between the predicted signal strength RSSI-infer and the actual signal strength RSSI;

[0100] A determination unit, configured to compare the calculated similarity with a preset similarity threshold to determine whether GPS spoofing occurs

[0101] In a possible design, the device also includes:

[0102] An acquisition unit, configured to acquire existing GPS signal training data, the GPS signal training data including traini...

Embodiment 3

[0108] This embodiment provides a GPS spoofing detection device based on RSSI, such as Image 6 shown, including:

[0109] A GPS signal receiver for receiving GPS signals;

[0110] memory for storing instructions;

[0111] The signal processor is configured to read the instructions stored in the memory, and execute the GPS spoofing detection method described in Embodiment 1 according to the instructions.

[0112] The memory may include, but is not limited to, random access memory (Random Access Memory, RAM), read-only memory (Read Only Memory, ROM), flash memory (Flash Memory), first-in-first-out memory (First Input First Output, FIFO) and / or Or first-in-last-out memory (First In Last Out, FILO), etc.; the signal processor may include, but is not limited to, a single-chip microcomputer, an ARM processor, and the like.

Abstract

The invention relates to the technical field of electronic communication, in particular to a GPS spoofing detection method and device based on RSSI and a storage medium. The method comprises the stepsthat a GPS signal is received, and the GPS signal comprises received actual signal strength RSSI and first longitude and latitude information; calculating according to the first longitude and latitude information of the received GPS signal to obtain predicted signal strength RSSIinfer; calculating the similarity DTW between the predicted signal strength RSSI-infer and the actual signal strength RSSI; and comparing the calculated similarity with a preset similarity threshold, and judging whether GPS spoofing occurs or not. The method can effectively solve the problem that an existing GPS spoofing detection method needs to upgrade hardware equipment to cause huge cost, and the defect that a part of defense methods have limitation in application range, so that a GPS receiving end can discover the occurrence of GPS spoofing conditions in time and take corresponding defense measures.

Description
