What is PD CEN/TR 17464 about?
The objective of PD CEN/TR 17464 is to analyse the security issues that can occur at the GNSS SIS (Signal in Space) level. This document proposes a full taxonomy of GNSS SIS attacks signals (voluntary or non-voluntary) and identify their impact on GNSS-Based Positioning Terminal (GBPT) positioning function. An opening concerning the jamming and spoofing threat categorization subject is provided describing two known previous categorization works. Then a taxonomy of GNSS attack signals is proposed and each attacks categories and types are detailed. Security metrics for the validation of the GBPT robustness performances are defined.
PD CEN/TR 17464 proposed methodology for this technical report consists in three distinct steps that are described below:
- The first step consists in providing a full taxonomy of the possible GNSS Signal in Space attacks (voluntary or not) to be considered and identify their impact at GBPT level
- The second step consists in regrouping narrow sets of previously identified GNSS SIS attacks into security attack models. For each security attack model, an assessment of the dangerousness based on beforehand identified key parameters and methodology will be provided
- The third step consists in providing definition of performance objectives, security control, security metrics, and a specific procedure for a robustness evaluation of a GBPT against the identified security attack models at step II

Why should you use PD CEN/TR 17464?
Security of the GNSS-Based Positioning Terminal in road Intelligent Transport Systems (ITS) is very critical. Many applications rely on PVT information provided by GNSS. If during the past GNSS SIS (Signal in Space) attacks were considered as feasible but requiring significant technical means, it is not the case today considering that a spoofing attack can be led with a Commercial-Off-The-Shelf Software Design Radio (COTS SDR) at relatively low cost and that jammer are available on the market at a wealth of prices.
PD CEN/TR 17464 provides guidance for the analysis of GNSS attacks taxonomy which helps receiver manufacturers began to implement new technologies fighting against SIS GNSS attacks and major advances that have been done in the GNSS security aspects in Europe associated to the new capabilities of the Galileo system in the definition of the public regulated service and the commercial authentication service.
PD CEN/TR 17464 describes security attack models which aims to regroup narrow sets of previously identified GNSS SIS attack signals into security attack models. Those security models are then classified in function of the dangerousness they represent. The assessment of the dangerousness level is performed based on key parameters and a methodology that are identified and defined in this document.
