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.
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)
From GPS-only, single-frequency receivers
to high-end GNSS, multi-constellation,
Featuring, on-board security, anti-jamming and anti-spoofing mechanisms.
Resilient architectures for long-distance accurate time distribution (e.g.: WR-PTP)
Autonomous switch between different GNSS time source
Integrity check and remote attestation of the software running on network devices
Secure network communication relying on trust computing
CORE TECHNOLOGIES IN ROOT
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.
THE PROJECT: PROGRESS TIMELINE
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 2021Accomplished
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 2021Accomplished
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.
