About ROOT

A MIX OF EMERGING TECHNOLOGIES:

ROOT aims to assess the benefits introduced by the Galileo authenticated signals (OSNMA) in the specific context of synchronization of 5G telecommunications networks. Specifically, ROOT purpose is to estimate the increased resilience that OSNMA can bring to GNSS-based timing sources. This is obtained through an experimental approach which enables the measurement of the increased level of robustness provided by the use of a mix of emerging technologies.

5G TELECOM NETWORKS

LTE-A, LTE-TDD and 5G introduce new stringent requirements to time and phase synchronization

Evolution to phase synchronization is done via Distributed Grandmaster Clocks (D-GMC)

RELIABLE GNSS RECEIVERS

From GPS-only, single-frequency receivers
to high-end GNSS, multi-constellation,
multi-frequency receivers

Featuring, on-board security, anti-jamming and anti-spoofing mechanisms.

NEW PTP MECHANISMS

Resilient architectures for long-distance accurate time distribution (e.g.: WR-PTP)

Autonomous switch between different GNSS time source

NETWORK SECURITY

Integrity check and remote attestation of the software running on network devices

Secure network communication relying on trust computing

THE PROJECT: AN EXPERIMENTAL APPROACH

The experimental approach is the core of the ROOT project. It has been devised in 4 steps to be implemented after the careful analysis of the state of the art in the different fields relevant to ROOT activities and the high-level definition of the system architecture.

01. SELECT THE ATTACK

Choose within set of radio-frequency and cyberattacks designed to impair time and phase synchronization in real 5G networks infrastructures

02. SETUP THE SYSTEM

Setup the experimental
testbed and reproduce
intentional attacks
to stress the network synchronization

03. RUN THE TEST

Perform the test
campaign at 5Tonic
labs and collect
data for post
processing analysis

04. ASSESS THE BENEFITS

Compare state-of-the-art with
new solutions,
featuring protections
from the selected
attacks. Quantify
the benefits of ROOT solutions


THE PROJECT: PROGRESS TIMELINE

November 2021
Ongoing

Test running at Telefonica Technology and Automation Lab

Telefonica is hosting the project partners in Madrid to run the tests and check the reliability of the ROOT solution. In paralell, OSNMA “Public Observation phase” has been recently started on Galileo, and ROOT testing activities are going to assess its application on secure timing networks.

October 2021
Ongoing

Preparation of the test bed

The ROOT team is preparing for the test campaign. In Madrid, Telefonica is setting up their labs with a high-end GNSS antenna, oscilloscopes and needed equipment, while in Torino Politecnico and LINKS are finalizing GNSS and Cybersecurity test procedures to be performed at the ROOT testbed facilities in a plug and play fashion. In the meanwhile, Septentrio and Seven Solutions are updating and integrating their products to make the ROOT solution ready to receive and use the new Galileo OSNMA signal along with remote attestation to protect the network from malicious attacks.

Mid-Term Review

The whole project consortium, the officers from the EUSPA (former GSA) and the external officers virtually met to discuss about the project. The meeting focused on the achievements of the project and the status of the tests. All the activities to be carried on in the second half of the project have been planned.

May – June 2021
Accomplished

Internal Workshops for business planning

The consortium virtually met two times to carry on brain storming activites for the definition and fine tuning of the ROOT business model.

April 2021
Accomplished

Scenarios and Test Plan definition

Design the test strategy for the different selected attacks. Definition of the test objectives for each test case and the measureable KPIs.
Resource planning: definition and procurement of hardware and software necessary to perform the attacks at signal and non-signal level, schedule and planning of the test logistics.

February – March 2021
Accomplished

Threats and synchronization vulnerabilities analysis

Definition of the vulnerabilities of the reference network architecture and identification of the most impacting attacks to GNSS time sources and transport hardware/protocols for the secure distribution of time synch.

December – January 2021
Accomplished

Definition of secure 5G network synchronization

Investigation of the state-of-the-art synchronization technologies in telecommunications network and definition of a realistic and comprehensive reference architecture supporting ePRTC synchronization.
