AI Technical Summary

Technical Problem

Existing communication mechanisms in 3GPP TS lack the reporting of GNSS spoofing attack detection results from UE to the server, necessitating an improved method to convey detection outcomes effectively.

Method used

Implementing an additional error cause and attack probability metric for UEs to report spoofing attacks to the server using server-UE authentication, leveraging authentication errors within a time window.

Benefits of technology

Enhances the reporting of GNSS spoofing attack detection results by normalizing the probability metric, thereby improving the server's decision-making process.

Abstract

This invention focuses on an additional error cause and an attack probability metric for UE to report spoofing attack to server. While the detection algorithm on UE and the decision algorithm on server can be open for implementations, this contribution proposes to leverage server-UE authentication mechanism and calculate the attack probability metric by the number of authentication errors within a time window.

Description

METHOD TO PROTECT UE FROM GNSS SPOOFING ATTACKFIELD

[0001] This invention focuses on an additional error cause and an attack probability metric for UE to report spoofing attack to server. While the detection algorithm on UE and the decision algorithm on server can be open for implementations, this invention proposes to leverage server-UE authentication mechanism and calculate the attack probability metric by the number of authentication errors within a time window.BACKGROUND

[0002] A paper describes the recent advances of detection of GNSS spoofing attacks to GNSS devices. The paper describes receiver architecture and algorithms that can be used to detect GNSS spoofing attacks on UE. Nevertheless, the communication mechanism of such detection results from UE to server is currently lacking in 3GPP TS compared to other communication standards.

[0003] This contribution proposes an extension to 3GPP TS to mitigate this issue with an additional error cause and an attack probability metric. This allows UE to report the detection result in normalized probability metric to the server side. While the detection algorithm on UE and the decision algorithm on server can be open for implementations, this invention proposes to leverage server-UE authentication mechanism and calculate the attack probability metric by the number of authentication errors within a time window.
