EN 16803-3:2020

Space - Use of GNSS-based positioning for road Intelligent Transport Systems (ITS) - Part 3: Assessment of security performances of GNSS-based positioning terminals

This document shall be considered as a complementary standard to EN 16803-2 that is intended to assessment of the performances of a GBPT placed in real-life or simulated road environments. This document is instead specifically targeting security attacks such as interferences, jamming, meaconing or spoofing. This document cannot be applied independently from EN 16803-2 that describes in details the general methodology of the assessment procedure.
This document provides normative information necessary to replay in the lab standardized scenarios specifically dedicated to security tests applied to GNSS.
Depending on the case (jamming or spoofing), these scenarios are composed of data sets combining either real life recorded SIS and jamming signals or simulated SIS and spoofing signals. The reason for that will be explained in Clause 6.
Although a high-level categorization of GNSS attacks is given in Annex A, a comprehensive and detailed categorization of possible GNSS attacks is out of the scope of this document.
It is not the aim of this EN to standardize the record procedure neither to define the specific requirements for the generation of the attack scenarios. The record procedure itself and its quality framework for accredited GNSS-specialized laboratories (Lab-A), with the detailed definition of standardized attack scenarios, will be totally and precisely described in EN 16803-4 (under preparation). The list of attack scenarios will have to be regularly updated considering the evolution of GNSS technologies, emerging threats, and countermeasures.

Raumfahrt - Anwendung von GNSS-basierter Ortung für Intelligente Transportsysteme (ITS) im Straßenverkehr - Teil 3: Überprüfung der sicheren Leistungen von GNSS-basierten Ortungsendgeräten

Das vorliegende Dokument ist eine ergänzende Norm zu EN 16803-2, die für die Überprüfung der Leistungsdaten eines GBPT in realen oder simulierten Straßenumgebungen vorgesehen ist. Dieses Dokument behandelt stattdessen speziell ausgerichtete Sicherheitsangriffe wie Störbeeinflussungen, Störsendungen, Meaconing oder Spoofing. Es kann nicht unabhängig von EN 16803-2 angewendet werden, die die allgemeine Methodik für das Überprüfungsverfahren eingehend beschreibt.
Dieses Dokument enthält normative Informationen, die notwendig sind, um im Labor genormte Szenarien, die speziell für auf GNSS zutreffende Sicherheitsprüfungen vorgesehen sind, wiederzugeben.
In Abhängigkeit vom Störfall (Störsendung oder Spoofing) setzen sich diese Szenarien aus Datensätzen zusammen, die entweder echte aufgenommene SIS und Signale von Störsendern oder simulierte SIS und Spoofing-Signale miteinander kombinieren. Die Gründe für diesen Ansatz werden in Abschnitt 6 erläutert.
Auch wenn Anhang A eine Einteilung von GNSS-Angriffen in übergeordnete Kategorien enthält, gehört eine umfassende und genaue Einteilung möglicher GNSS-Angriffe nicht zum Anwendungsbereich des vorliegenden Dokuments.
Ziel dieses Dokuments ist weder die Normung des Aufzeichnungsverfahrens noch die Festlegung spezifischer Anforderungen für die Aufstellung der Angriffsszenarien. Das Aufzeichnungsverfahren selbst und sein Qualitätsrahmen für bevollmächtigte auf GNSS spezialisierte Labore (Lab-A) mit der genauen Definition der genormten Angriffsszenarien werden vollständig und eingehend in EN 16803-4 (in Vorbereitung) beschrieben. Die Liste der Angriffsszenarien muss unter Berücksichtigung der Weiterentwicklung der GNSS-Technologie, auftretender Bedrohungen und Gegenmaßnahmen regelmäßig aktualisiert werden.
