Why GNSS-based Positioning?

GNSS-based positioning is at the forefront of modern ITS due to its ability to provide precise location data, which is crucial for the development of smart transportation solutions. This technology enhances the accuracy of navigation systems, supports real-time traffic management, and facilitates the deployment of autonomous vehicles.

Security: A Top Priority

As ITS becomes more reliant on GNSS technology, the potential for security threats increases. The PD CEN/TR 17464:2020 standard addresses these concerns by offering a detailed framework for modeling security attacks. It outlines the necessary performance features and metrics to ensure that GNSS-based systems are resilient against potential threats.

Security Attack Modeling

The standard provides a comprehensive approach to identifying and mitigating security risks associated with GNSS-based positioning. It includes:

• Identification of potential security threats and vulnerabilities.
• Strategies for modeling and simulating security attacks.
• Guidelines for developing robust security measures.

Performance Features and Metrics

To ensure the effectiveness of security measures, the standard defines key performance features and metrics. These metrics are essential for evaluating the security posture of GNSS-based ITS solutions and include:

• Accuracy and reliability of positioning data.
• Response time to security threats.
• Effectiveness of security protocols and countermeasures.

Applications in Road ITS

The integration of GNSS-based positioning in road ITS has numerous applications, including:

• Traffic Management: Real-time monitoring and management of traffic flow to reduce congestion and improve safety.

PD CEN/TR 17464:2020

This standard PD CEN/TR 17464:2020 Space. Use of GNSS-based positioning for road Intelligent Transport System (ITS). Security attacks modelling and definition of performance features and metrics related to security is classified in these ICS categories:

• 03.220.20 Road transport
• 33.060.30 Radio relay and fixed satellite communications systems
• 35.240.60 IT applications in transport

The objective is to analyse the security issues that can occur at the GNSS SIS level. In order to do so, a full taxonomy of the GNSS SIS attacks are proposed and GNSS SIS attack security model are elaborated and classified. Security metrics for the validation of the GBPT robustness performances are defined.

The proposed methodology for this technical report consists in three distinct steps that are described hereunder:

• 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.
